DiffMerge may do what you need:

Performs a side-by-side comparison of 2 folders, showing which files are only present in one file or the other, as well as file pairs which are identical or different.

Graphically shows the changes between two files. Includes intra-line highlighting and full support for editing.

If you have the developer tools installed, you will have filemerge, which can compare 2 directories. However - if you haven't it would be a rather big thing to install just for that.

I use "Beyond compare" to do it, and it seems that the MAC equivalent is bbedit

Absolutely not. BBEdit is a general purpose and developers' text editor that perhaps has some diff functionality. – Daniel Beck Jan 5 '11 at 12:02

If you don't mind using the command line, you can use the UNIX 'diff' command.

An example of a command to run a compare using diff could be:

diff -r /my/first/directory /my/second/directory

This will recursively perform a diff on all common directories and files between the two directories.
