Hello, this is probably a silly question, but... How do you specify versions of ports to be installed? I tried upgrading ghc from 6.6_2 to 6.6_3 but the compile fails. I now want to have my old version back, of which I still have a package. I am in /opt/local/var/db/dports/packages/darwin/powerpc I can see that I have several packages of ghc, including the one that I want 6.6_2 $ ls ghc* ghc-6.6_0+darwin_8_powerpc.powerpc.tgz ghc-6.6_2+darwin_8_powerpc.powerpc.tgz ghc-6.6_1+darwin_8_powerpc.powerpc.tgz I want to install it: $ sudo port install -b ghc @6.6_2 Error: Target com.apple.unarchive returned: Archive for ghc 6.6_3+darwin_8_powerpc not found, required when binary-only is set! Error: Status 1 encountered during processing. Why does this not work? What do I need to do? Thanks, Max
