about sys-fs/zfs-fuse and qmerge
 

I need a little coaching on qmerge usage.

I'm trying to emerge sys-fs/zfs-fuse. The merge fails on a known bug,
a duplicate of another bug... 303623
http://bugs.gentoo.org/show_bug.cgi?id=303623

In the comments... (#3) someone has asked to make the emerge once a
specific file is edited to remove Werror calls.

Someone replies with these few lines:
ebuild /path/to/ebuild unpack
edit the file
ebuild /path/to/ebuild compile then install then qmerge

I did `ebuild unpack'
Found the file and made the necessary edits.

Then ebuild install.

But now looking a t man qmerge... its not at all clear how to install
this compiled package with qmerge

qmerge <opts> <pkgnames>

Would pkgname be the binary `make' left in the build directory at:
/var/tmp/portage/sys-fs/zfs-fuse-0.5.0/work/zfs-fuse-0.5.0

under:

ls -F ./src/zfs-fuse/zfs-fuse:

src/zfs-fuse/zfs-fuse*

so something like `qmerge src/zfs-fuse/zfs-fuse*'
The man page does say its for intalling binaries.

I just don't want to make some mess thats hard to clean up and would
rather hear from someone who knows how to use `qmerge'.

Or even better some other work around.... The tail of the original
emerge failure is inlined below. But its the exact output shown in
the bug referenced above. And is the result of having Werror calls in
the CCFLAGS

There's even a patch from a previous duplicate bug its a simple edit
but then you have to go thru creating an edited ebuild and yatta
yatta.
