mftrace problem (fwd)

[Ladislav Michnovic]

Hello. 
 I have a problem with mftrace program, when generating fonts for lilypond 
from metafont it fails on i386 arch. On AMD x86_64 it's ok.
lilypond-2.6.3/mf> mftrace --encoding feta11.enc --no-afm -I ./out/ 
--formats=pfa,pfb,svg feta11
mftrace 1.1.12
Font `feta11'...
Warning: no extra font information for this font.
Consider writing a XX_guess_font_info() routine.
Using encoding file: `./out/feta11.enc'
Running Metafont...

/usr/bin/gf2pbm: command exited with value 512 (ignored) Too many bits 
found when loading character 34warning: /usr/bin/gf2pbm: command exited 
with value 512 (ignored) Too many bits found when loading character 
35warning: /usr/bin/gf2pbm: command exited with value 512 (ignored) Too 
many bits found when loading character 36
etc.

Can you please give me a advise, what's wrong?
Thank you.
