Upgrading to Mavericks, I appear to have broken my Ruby on Rails development environment, which requires ruby 1.9.3 because of various gem dependencies. Within that app directory, I'm trying to reinstall ruby 1.9.3-p547:
rvm reinstall ruby-1.9.3-p547
I then get an error:
checking whether the C compiler works... no configure: error: in `/Users/dsfaulkenberry/.rvm/src/ruby-1.9.3-p547': configure: error: C compiler cannot create executables
Looking at the config.log file (~/.rvm/src/ruby-1.9.3-p547/config.log), I see:
dyld: Library not loaded: /usr/local/opt/cloog-ppl015/lib/libcloog.0.dylib Referenced from: /usr/local/Cellar/gcc46/4.6.4/gcc/libexec/gcc/x86_64-apple-darwin12.4.0/4.6.4/cc1 Reason: image not found
I can see that other people have encountered issues vis-à-vis upgrading to Mavericks and having c compiler issues, but I can't find any referencing this specific library or what I should do (reinstall gcc? is that even a thing I can do?)
Many solutions mention accepting an XCode license agreement, which I have done, and the problem persists.
A Stack Overflow user suggested uninstalling gcc through homebrew which I have done to no avail, and another user has suggested reinstalling homebrew itself, which I will try.
