Help! GD, PHP, Fonts and Linux

[darwin2kx]

I am new to GD, and just got a proper webserver set up on FreeBSD. I've managed to get GD to do a lovely bar graph. Now, I want to put text on it, but can't figure out what fonts I have installed for use.

How can I determine what fonts are available for use in my FreeBSD system?

In order to use True Type fonts you can use the ImageTTFText() function and specify the path to a .ttf file.
