Consequently, I can't see any relative location to which we can extract a GCC bootstrap, and /var/tmp is the best absolute path that I can think of for this purpose.Incidentally, I used otool on the executables in the current ghc bootstrap compiler, and they contain _absolute_ references to /opt/ local/lib/libgmp.3.dylib, so for those who try to install MacPorts ghc and who have configured ${prefix} to be other than /opt/local, the build will either fail due to the non-existence of /opt/local/ lib/libgmp.3.dylib, or (in accordance with the dyld(1) man page's description of the DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH variables), it will silently pick up libgmp.3.dylib in another location, such as /usr/local/lib, when it is run. I haven't looked into it, but we may find that the ghc bootstrap actually has this same problem, just not in such an obvious or severe form.As always, your thoughts (and those of others on the list) would be appreciated.
If it's just the libraries in the bootstrap compiler that are a problem, then you could do the temp install into somewhere like $ {worksrcpath} and set DYLD_FALLBACK_LIBRARY_PATH ...
