First -- make sure you have those library/object files installed FOR
THE TARGET ENVIRONMENT!. If you do have them, what directory are they in...

Second -- only if you do have them -- make sure the directory (or
multiple directories) are listed in the LD_LIBRARY_PATH environment
variable for the cross-build..
