On Linux you use "ldd" to find out what the linker will do with
dependencies of an executable or shared library. I don't recall the
equivalent incantation on FreeBSD or OS X but I'm sure there is one.
Note that this is very likely to depend on environment (eg
LD_LIBRARY_PATH) so make sure you do it in the same environment the
buildfarm test has.
