I can’t use gSystem.CompileMacro() when I use all three of [ root6, OSX and PyROOT ].
I do not have problems with [root6, SLC, PyROOT] or [root5, OSX, PyROOT].
Details:
In the “lab”, on an SLC6 machine, I can use PyROOT to do this successfully:
##############################################
pcil–bash$ root-config --version

pcil–bash$ cat << EOF > moo.cxx
int moo() { return 7; }
EOF

On my osx macbook (intel), where I have root6 (version 6.03/03) installed via macports, PyROOT does not succeed any more:

However on the same osx macbook I can succeed if I DON’T use PyRoot, instead using ROOT directly:

Note, with root5, there are no problems on EITHER machine – so the problem seems to involve all three of osx, root6 and pyroot.
Ideas?
