I am trying to install Rails on OS X 10.7.5, using Homebrew and continue to receive the below Warning. I have tried many times to change the PATH to exclude the Python Directories (modifying .bash_profile, but am not even sure this is what is causing the Warning. Apologies if this is serious noob territory, but I could not find anything helpful after hours of searching. Homebrew warning:
Warning: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following “config” scripts:
/Library/Frameworks/Python.framework/Versions/Current/bin/python-config
/Library/Frameworks/Python.framework/Versions/Current/bin/python2.5-config
/opt/sm/pkg/active/bin/curl-config
/opt/sm/pkg/active/bin/ncurses5-config
/opt/sm/pkg/active/bin/ncursesw5-config
/opt/sm/pkg/active/bin/pkg-config
/opt/sm/pkg/active/bin/xml2-config
/opt/sm/pkg/active/bin/xslt-config
I think you should make installation of Rails using gem tool . Rails is just a gem and in should not be installed by homebrew . First install the newest version of Ruby , then google a little about gem management system and give it a go . Here is a nice Railscast on the subject.
