Sending him an email should work. His email address is part of the output produced by running the command "port info llvm-3.2".

As far as I know, llvm-3.2 should still build on Mavericks, though it is not supported on Yosemite at this time. However, newer versions of llvm are available, so you should probably use those, as you're trying to do.

Which dependencies? To find out, run:

port installed depends:llvm-3.2

Two common ports that depend on llvm are cctools and ld64. They have variants for selecting which version of llvm you want to use. They default changes, as newer version of llvm are released, however once you install the port, MacPorts ensures the same variant continues to get used. So it could be that you initially installed cctools and ld64 back when llvm32 was its default variant. You could fix that by reinstalling ld64 with its now-current llvm34 default variant, and then doing the same for cctools, by running:

sudo port install ld64
sudo port install cctools

Or if you prefer to use the older llvm-3.3 instead of the newer llvm-3.4, you could:

sudo port install ld64 +llvm33
sudo port install cctools +llvm33

Assuming no other installed ports still depend on llvm-3.2, you should then be able to uninstall the old ld64 and cctools ports and llvm-3.2 itself.
