I have uploaded a linux WIP build:

http://psxemulator.gazaxian.com/pSX_wip.tar.bz2

You will need linux kernel >=2.6, GTK+-2.0, OpenGL, ALSA and perhaps some other things I have forgotten.

Please note that this is not finished although most stuff is working except the CDZ conversion dialog and some of the error message dialogs.

I would be interested to hear if anyone is able to run it and whether or not you have any problems

This is my first ever Linux app so please be kind
