i have 32 bit lenny running. ( i cannot upgrade)
i need to install mysql-server-5.1 amd64 on it.

This system is already running l 64 bit kernel.

i can't seem to find that package in any current repo so i'm thinking of force installing it using dpkg but i don't know how to solve dependencies (especially libraries)

Any advice?

I recommend that you learn about chroots. Then use 'debootstrap' to
install a Squeeze chroot on your Lenny system. Install mysql in the
Squeeze chroot. Run it from there. That will allow you to have a
Stable Squeeze "system" in the chroot with newer production quality
code than you can in the host system.

Then understand why you cannot upgrade your lenny system. Identify
the parts that don't want to move. Do the reverse. Build a Lenny
chroot. Move those problematic components that are holding you back
into the Lenny chroot. That will free you to upgrade your host system
to Squeeze and get security upgrades for most of your system. Then
work to remove those Lenny parts that are stuck.

I run daemons in chroots all of the time for just such reasons. No
time now but if you are interested I could write up a quick recipe for
doing this.

And the compelling reason for doing so is...? (just curious)

IIUC, he currently has a 64 bit kernel of unstated origin, with 32 bit
Lenny user space, and he's unable to upgrade the user space to 64 bit Lenny.

Without more details of that 64 bit kernel, are you sure your advice to
install a 65 bit Squeeze chroot is salient? The kernel may be the
reason he's unable to upgrade user space to 64 bit, depending on what
was/not built into it.

It may be a lot less work to simply provide details about the kernel.
He may be able to simply replace it and fix the whole thing in one swing
of the bat.

Yes.

He didn't say he couldn't upgrade to 64-bit. He said he couldn't
upgrade. I assumed that meant that he could not upgrade to Squeeze.
Lenny mysql is 5.0 with mysql-server-5.1 and that difference
distracted me.

But you are right. I didn't connect the dots with his request to get
mysql amd64 running. I missed that point entirely. Thanks for
pointing the point out.

I may have been accidentally okay. Because if he is running a 64-bit
kernel then it should be possible to run a 64-bit userland in a
chroot. I am pretty sure that will work okay. Even from a Lenny
amd64 kernel to a Squeeze amd64 userland. At the worst it won't work
and his current system won't be damaged.

Well... Normally it isn't possible to upgrade from 32-bit to 64-bit.
Normally that would be a full system reinstall. However there are
reports of people successfully doing it.[1][2][3] But it isn't a
normal upgrade. It is an expert sculpting of artwork in place.

Originally I thought it was some other reason the he could not
upgrade. I have systems myself that I can't upgrade due to binary
blobs of dynamically loaded lib.o files.

I don't think knowing more about the kernel will help. Especially now
that you pointed out the 32-bit userland and wanting a 64-bit mysql.
That seems the critical point.

I tend to agree. At this point I'm thinking his best option may be
installing a 64 bit KVM or Xen kernel and running his current system as
a guest, if such a retrofit is possible (haven't tried it). Then
install a new 64 bit guest Squeeze system w/mysql.

The OP left out important details, such as whether the box is a server
or a workstation, needs to run a GUI desktop or not.
