pgmonitor on solaris

Hi

Is there a pgmonitor version for Solaris?? It dies with:

Can't run 'ps': awk: syntax error near line 3
awk: illegal statement near line 3
awk: illegal statement near line 4
Please send in a patch.

I tried to fix it whith:

1 - correct the path to ps.
2 - convert Linux ps args to Solaris 2.5.1 ps args.

Step 2 did not work, I could not find equivalents to x,w args and I do not 
know if it is the only think that must be fixed.

Thank you
