I just installed Mavericks and I tried brew install scala to install scala language but it failed.
Then I typed brew update but still installation of scala fails.
So I post the brew doctor command to help readers of stackoverflow helping me with this problem.
Here is the result :
$ brew doctor

./configurescripts 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:
/opt/local/bin/libpng-config /opt/local/bin/libpng15-config /opt/local/bin/ncurses5-config /opt/local/bin/ncursesw5-config /opt/local/bin/pkg-config /opt/local/bin/xml2-configWarning: You have MacPorts or Fink installed: /opt/local/bin/port
This can cause trouble. You don't have to uninstall them, but you may want to temporarily move them out of the way, e.g.
sudo mv /opt/local ~/macports
