/usr/local/lib and /usr/local/include must be empty, or at least not contain anything that might be used by the python build. AFAIK it is practically impossible[1] to tell the compiler to exclude /usr/local from its search paths. Fink and Macports must be disabled because Python's setup.py actively looks in those directory for dependencies (such as for BerkelyDB). I wouldn't mind having a configure switch that disables looking in the default Fink and Macports trees, but don't have time to work on that myself. BTW. Excluding these locations is only needed when building the official installer, you can obviously just keep them around when you build and use Python locally. I tend to move /usr/local aside when I build the installer and move it back afterwards, and have used an mostly empty virtual machine for the last couple of releases. Ronald [1] that is, the only way I've found it to tell gcc not to use any search paths at all and manually specify all search paths, including compiler-specific directories. > > Skip
