Hi Arlindo, Some comments to your questions 0) I was an astronomer and now I also am an atmospheric scientist/ meteorologist. I am now building a sort of PDL "integrated" solution which I called SAPO (sapo.sourceforge.net) which has already many features but needs some update. 3) I don't know about static builds, but the Linux distribution that has better binaries of PDL is Debian or the Debian based systems (Ubuntu, etc). The only package now missing is the PGPLOT Perl one which has been orphaned, but is anyhow easy to compile. 4) To have RGB support you need to path the current version of PGPLOT with a patch that has been circulating around in the mailing list (I will try to find it for you). You also need the latest version of the Perl PGPLOT package. This procedure would clearly need to be explained in the Wiki pages. The reason for going through all this cumbersome process is due to licenses issues with PGPLOT.
