I'm not sure what to do about those ports that depend on swig30 in the presence of swig20 also being installed, given they don't appear to CONFLICT_INSTALL on each other. They both can't provide the swig symlink. Supporting swig in DEFAULT_VERSIONS doesn't sound right and is probably overkill. > In our ports, we name our swig binaries things like > "/usr/local/bin/swig2.0" or > "/usr/local/bin/swig3.0". How do we deal with this in Python ports which > use > SWIG? If this is the case, it would mean all swig dependent things are also broken. How are other ports dealing with it, or working? This might provide some insight. The if os.name == "posix": branch could do the same swig version-suffixed binary checking that the elif os.name == "nt": condition branch does. A smarter way might *also* be to add functionality to that swig method to allow the system to provide the binary path/name via envvars or command line argument to (build,build_ext) commands explicitly. I suggest creating an upstream issue. > If possible, I'd like to push a fix upstream for FreeBSD, if the upstream > maintainer > is OK with it.
