I tested the slang frontend by hand, and discovered that slang.so require libm. Checking /usr/bin/mklibs I discovered this text:
# HACK: exclude libm, since we don't need it for anything I believe this hack must be removed to get the slang frontend working. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
