Win! It’s written in pure Perl, very easy to install (doesn’t even use CPAN if you don’t want).

It recurses into subdirs by default, while ignoring stuff like revision control and binary files. You can search specific types of files through a symbolic name rather than by specifying regexes. And it has colour highlighting, and simply uses the familiar Perl regexes for its pattern matching rather than funky subsets of which there are many distinct ones…
