DYLD_LIBRARY_PATH to find it, and using gcc-4.2 to compile R, all is well.


FWIW suspect that your system is pretty badly messed up with all the 3rd-party stuff you installed, because our 64-bit binaries don't need any of this... see
http://r.research.att.com/

Also note that messing with DYLD_LIBRARY_PATH is really dangerous and causes a lot of problems since it overrides *all* system path searches (unlike LD_LIBRARY_PATH on Linux).

Cheers,
Simon

The solution to the readline problem was to remove all conflicting

you should 'make docs' now ...
building/updating package metadata ...
dyld: lazy symbol binding failed: Symbol not found: _libiconv_open

installing a fresh 32/64-bit libiconv and removing all conflicting
versions has not helped.

i built readline 6.0 from source with the -arch x86_64 switch on gcc
