Since sys-libs/zlib-1.2.5-r2 appeared, media-gfx/fontforge is not able to open PDF files anymore. It lists their fonts, but when trying to open any of them, it just says "/usr/lib64/libz.so: invalid ELF header" and "Unsupported filter: FlateDecode". Both media-gfx/fontforge-20100501 and 20110222 are affected. The problem seems to be in fontforge, as the zlib part is WONTFIX according to bug 290974. media-sound/lilypond is suffering from a similar problem as bug 334835 shows. $ emerge --info fontforge zlib

Created attachment 273705 [details, diff] A suggested patch for media-gfx/fontforge-20100501 This patch fixes the problem by always trying to open "libz.so.1" if "libz.so" fails. The idea has been taken from the files "gutils/gimagereadpng.c" and "gutils/gimagewritepng.c" of the source code. I hope that for other libraries beyond zlib we don't need such fixes.
Created attachment 273709 [details, diff] An analogous patch for media-gfx/fontforge-20110222 If OK, should these patches be sent upstream?
I've reported this issue upstream. We'll see what George tells us.
I have been having the same problem when fontforge is called during the installation of media-sound/lilypond. I think this bug can be marked as "confirmed". Siim's patch for media-gfx/fontforge-20110222 works for me, on an otherwise x86 (mostly x86 not ~ x86) system. For anyone else needing to try this (or wanting to test): Just copy the ebuild to your local overlay, add an extra epatch line in src_prepare() and all's good.
i confirm that the patch works and solves the problems i was having when trying to compile lilypond.
Peter, any updates here from upstream? I'm working on bumping lilypond to latest stable version and I hit this fontforge bug too.
Siim's patch helped me too so that I was able to build lilypond-2.14.2.
Patch was added in 20110222-r1. Thank you for report and fix. Unfortunately upstream keeps silence on this issue at the moment.
