Ray is correct here and I think, possibly closing in on the problem. I
have seen this problem when the .so links aren't built right.

Normally there is a .so link, a .so.X link and a .so.X.YY dynamic library.
The linker will sometimes not follow a symbolic link more than one link,
so, if the .so link is to .so.X with .so.X linked to the actual library,
the linker will fail to find the library. Change the .so link to point
to the acutal .so.X.YY library and the compilation should get much better.

Note: This is only likely if updating binutils (as suggested by Ray)
doesn't fix the problem. You should try that idea first.

Luck,

Dwarf
