Yes, that is already better :). However, those should be just  
warnings, not errors - does affyplier.so exist? Once R is started,  
the DYLIB_LIBRARY_PATH is set and dyld should find the libraries.

If not, then it really depends on your compilers - check libR.dylib  
and the others in /usr/local/lib64/R/lib with otool64 -L to see where  
they are actually expected. If in doubt, send me the output of
otool64 -L /usr/local/lib64/R/lib/*
and
otool64 -L /usr/local/lib/libg*
