Hello B, Thanks for your help. After running pkgdb -F, I find that there hundreds of ports depending on python2.5. Looks to me it will be easier to backup my dstfiles and reinstall the whole system afresh a 3rd time rather than trying to fix the existing ports. This time I will install no packages from the installation media, and build directly from ports instead. The first 2 ports I will build this time will be lang/python26 followed by lang/python. I suppose this should set the systemwide default python version to 2.6. Before I undertake this 3rd attempt, I request a few clarifications so that everything comes out fine this time around. >> something is wrong -- perhaps you have PYTHON_VERSION or PYTHON_DEFAULT_VERSION >> defined to the wrong value, or your ports tree is corrupt.

If you've >> stale ports that are still wired to use python2.5 for no good reason, >> you can patch them or their port Makefiles, or put a workaround in >> make.conf. 1) How do I find or set PYTHON_DEFAULT_VERSION ? 2) What workaround would be needed in make.conf to get 2.5-hardwired ports to use 2.6 instead ?
