I've just installed PSRCHIVE using PSRsoft. The installation seems to work perfectly; The commands psredit, psrstat, psrsh etc. all work fine. However when I try to call psrplot I get a 'command not found' error. I expect PGPLOT is the problem, since running pav also returns a 'command not found' error, and as far as I understand both pav and psrplot rely on PGPLOT.
Does anyone know how I can add PGPLOT to my installation.
edit - OS is Ubuntu 12.04
