My first thought would be that maybe the C library in question isn't
actually installed or that you need the dev version of the package
installed, and it isn't. If it can't find the symbols, maybe they just
aren't currently there. Alternatively, maybe it's not on your library load
path - though I would have expected something like that to be installed in
/usr/lib, which would definitely be in your library load path.

BTW, questions like this are better suited to the D.Learn newsgroup/forum.
