Hmm, OK. I don't know which this person was using. Why is /usr/lib/wine even added to ld.so.conf though, surely that isn't necessary? Only libwine needs to be in the linker path.
libs are in /usr/lib/wine and dlls are in /usr/lib/wine/dlls, not adding /usr/lib/wine to ld.so.conf causes wine to fail, as it doesn't find ntdll.dll.so. There are alternative solutions, but this looks good to me, keeps dirs tidy and has always worked.
