How I eventually got the build working (thanks mucho to Kjell
Konis who maintains the R port for MacPorts):
+ I had to make a small change to setup.py. In the elif
+ sys.platform=='darwin': block I added 'Rblas' to the libraries. That
+ is I changed libraries=['R'] to libraries=['R','Rblas']. Then, after
+ setting the following 2 environment variables
+
+ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`R RHOME`/lib
+ export MACOSX_DEPLOYMENT_TARGET=10.4
+
+ rpy built fine using the Apple supplied gcc 4.0.1.
Also there were some linking problems in the rpy so's that I had
to fix with otool:
BAD:
$ otool -L _rpy2050.so
_rpy2050.so:
libR.dylib (compatibility version 2.5.0, current version 2.5.0)
libRblas.dylib (compatibility version 0.0.0, current version
0.0.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.1.9)
FIX WITH:
$ install_name_tool -change libR.dylib /opt/local/lib/R/lib/
libR.dylib _rpy2050.so
$ install_name_tool -change libRblas.dylib /opt/local/lib/R/lib/
libRblas.dylib _rpy2050.so
