I had some serious unexpected fun trying to install erlang on my OS X box using MacPorts. In general it’s usually a no brainer you usually type sudo port install <foo> and you have a new package installed without that much fuss. However here is the partial log of trying to install erlang and it blowing up…

Pretty sucky, huh? My first lazy thought was, “I thought the point of a package manager was to avoid all these problems.”
After a little bit of thinking and staring at the error message, I did the workaround and moved the /usr/local/include directory away and tried rebuilding which made things much happier. Check the log below…
$ cd /usr/local l$ ls arm-apple-darwin include man bin info share docs lib etc libexec $ sudo mv include include.ignore l$ sudo port install icu erlang Skipping org.macports.activate (icu ) since this port is already active ---> Cleaning icu ---> Building tcl with target all ---> Staging tcl into destroot ---> Installing tcl 8.5.1_0 ---> Activating tcl 8.5.1_0
Voila. A working erlang install. Don’t forget to move back the include directory back to its old place.
