error: cannot compute suffix of object files: cannot compile

[Bruce Korb <bruce dot korb at gmail dot com>]

Hi,

What does this message really mean?
i.e. What should I do about it?
ld.so should be loading shared objects in /usr/local/lib,
and that is where libmpc.so lives, so what gives?

Thanks - Bruce
