Yes, absolutely. So it would be best not to manually rename MacPorts installation prefixes, and instead build two separate MacPorts installations, in two separate prefixes, and use them from there. I personally prefer to have the tclpackage, applications-dir and frameworks-dir all inside the prefix so they're nice and self-contained. My MacPorts build script contains something like this:


PREFIX=/mp

./configure \
--prefix=$PREFIX \
--with-tclpackage=$PREFIX/Library/Tcl \
--with-applications-dir=$PREFIX/Applications \
--with-frameworks-dir=$PREFIX/Library/Frameworks \
--enable-readline

Those recommendations sound basically reasonable, with the exception of a few typos which I've now corrected. If you have any questions about the recommendations made there or need clarification, please ask; we could probably help here, as could I imagine the Inkscape people.
