Things are a bit different on OS X.  I've been running configure like
this:

../../src/R-devel/configure --with-blas="-framework vecLib" \
  --with-lapack --with-aqua

I'm not sure if one still needs to specify all of these with the
latest R-devel.

With this configure I get in my build dir $TOP/lib/libR.dylib and this
may be what you need for rpy (haven't tried, not sure).

Pretty sure that on OS X what you want is DYLD_LIBRARY_PATH and so
adding the lib dir might be worth a try.

HTH,
