Installing Mercurial on Mac OS X 10.6

For me, it wasn't the $PATH variable. That was already set to /usr/local/bin. However when I ran sudo su and performed ls -al /usr/local, bin was set only to 700 with "wheel" user. Though, probably not the most secure, I set this to chmod -R 755 /usr/local/bin and then I could run hg --version from any command line (as well as IntelliJ)
