I have the latest version of Mercurial installed on a fully patched Lion and the Mercurial client cannot be accessed from the terminal ("command not found"). The command line client is installed in /usr/local/bin and I've checked that this directory is in my $PATH variable.
The funny thing is that if I log on as the root user via sudo, I can access the command line client! I've checked the permissions of hg and it's +x for all users.
What could be wrong?
