The version difference is probably due to symbols stuff, read deb-symbols(5), dpkg-shlibdeps(1), dpkg-gensymbols(1) and this wiki page: http://wiki.debian.org/Projects/ImprovedDpkgShlibdeps No idea about the other stuff, you appear to have four copies of the C library installed and are maybe attempting multiarch cross-compilation, which isn't supported properly yet. -- bye, pabs http://wiki.debian.org/PaulWise
