[Wine] 32-bit libmpg123 on Gentoo

[Das Letzte Einhorn]

I noticed something strange today when testing TES3 : Morrowind. I use 64 bit Gentoo.

Despite having the libmpg123 files installed as part of my x86-soundlibs emulation package : http://bugs.gentoo.org/show_bug.cgi?id=283912 , mp3 playback still does not work. I ran a configure command on my wine source and I still get this message : configure: libmpg123 32-bit development files not found (or too old), mp3 codec won't be supported.

The x86 libmpg123 files I have are : 

/usr/lib32/libmpg123.so.0.20.3
/usr/lib32/libmpg123.so.0
/usr/lib32/libmpg123.so

/usr/lib32/mpg123/output_pulse.so
/usr/lib32/mpg123/output_portaudio.so
/usr/lib32/mpg123/output_oss.so
/usr/lib32/mpg123/output_jack.so
/usr/lib32/mpg123/output_dummy.so
/usr/lib32/mpg123/output_alsa.so

Is there anything missing for this to work?
