 Hadn't really considered which version to use ......... but obviously should.   Since opt installs itself at the head of the PATH, it always finds that version first.   I saw some discussion by you about specifying a GRASS_PYTHON - does that work and if so can you please provide details.  Came across this which seems relevant to the 32 / 64 bit issue.

The Python that comes with 10.6 apparently honors an environment variable called VERSIONER_PYTHON_PREFER_32_BIT. If that's set to 'yes', invoking Python from /usr/bin/python brings Python up in 32-bit mode. By default, it comes up in 64-bit mode.

Curious that I don't have any problem running the wxpython gui with GRASS 6.4
