I just installed kubuntu 6.06 on a new laptop (no binary avail), AMD64.
Compiling wine failed as 4979 says, no libfreetype.so that is compatible.
The problem is not in the -L or in gcc or in wine.
The problem is in the m32 libfreetype. /usr/lib32 is searched (as /usr/lib/../lib32) by gcc automatically with -m32.
The libfreetype developer(s) provided libfreetype.so.6.3.8 and link libfreetype.so.6 ->libfreetype.so.6.3.8
However they forgot to create the symlink
libfreetype.so -> libfreetype.so.6
Create this by hand in /usr/lib32 and regrettably wine still will not build as 4 externs are left unresolved: inflate, inflateReset,inflateEnd, inflateInit2.
This appears to also be a libfreetype issue. It's been reported several times in various contexts, google for 'libfreetype inflate' to see them.
I don't have a solution, sorry.
