Please, can you attach the full build.log and paste your "emerge -pv silo" output?

@base-system: any help appreciated. I'm sending this upstream anyway
Sorry guys, I didn't forget this bug, I am due to rebuild another SPARC chroot in a near future (this week I hope), will do a follow-up on the subject.
i dont understand what you need. e2fsprogs uses posix_memalign, so provide it in silo if you want to use the libraries. the function is pretty trivial to implement -- just read the desc of it in `man posix_memalign`. all you need is like a call to malloc with some bit twiddlin.
Have you tested silo-1.4.14_p20100228 with e2fsprogs-1.41.14 yet?
I reported this upstream. Testing is appreciated, as far as i've tested, it builds but silo breaks.
Patch is in http://marc.info/?l=linux-sparc&m=129468771631829&w=2
I've just patched silo with the patch from Dave Miller, and have tested it by installing new bootblock with silo -f, then rebooting. It will not boot - unknown ext2 error: 4294967295.
I have just looked at this again this morning. There appears to be a problem with the patch from David Miller, I had to spin a new patch based on it to be able to apply it cleanly to the e2fsprogs sources. I then tried to build both unstable e2fsprogs, that went well. Silo compiled OK and was installed to /boot. On reboot, I got the same error that I had the night before. I strongly suspect that posix_memalign() does need to be implemented or linked from glibc as a static function (maybe extract what we need?) otherwise silo fails to boot. New ebuild and patch attached.

OK, I have now a newer ebuild and a new patch that solves this problem entirely for all current versions of e2fsprogs/e2fsprogs-lib (<=1.41.14), attached to this bug report. Please test.

Nice job Alex, would be good to add a little note like "Required by e2fsprogs >= 1.41.14", remembering the role of a "callback" function is not trivial to guess. Will test when I will have 2 minutes.
Fixed
Thank you, AFAK corrections are in silo-1.4.14_p20100228
