Sorry for being dense: could you explain what diff is needed?
I unpacked R-patched_2005-05-12, and set:
OBJECT_MODE=64
CC=xlc_r
F77=xlf_r
CXX=xlC_r
CFLAGS/FLAGS/CXXFLAGS="-O -qstrict"
Running make gave similar error, namely symbols that should be in libm
not found. Below is output from BUILDDIR/libtool --config:
