emerge LyX fails on PPC only here

[lsm]

Building on a G3 ibook, emerge lyx fails here. It builds perfectly on x86 platforms with the same kernel (2.4.7-r14) and gcc (3.4.1) versions.

This is where the build fails. Please let me know if there is anything else I can tell you, and any ideas you may have. Thank you.

Just for reference, I have LyX on my iBook. I compiled with gcc 3.3.3_pre20040408-r1, or whatever version was previously stable on ppc.

Are you using plain gcc-3.4.1? From a message I saw on the ppc-dev list last week, it looks like 3.4.1-r2 is the go at the moment.

I found the fix somewhere, can't really remember where... (lyx-devel mailinglist, supposedly)

apply the following to the ebuild:

[lsm]

It compiled cleanly here with the patch, under 3.4.1. Thank you very much!

Stepping back to 3.3.3 (with gcc-config) was not a solution, however.
