Cool -- it works. You need the GNU scientific libraries gsl, and the plplot
plotting package installed. (Although the configure scripe checks for these
it doesn't exit with an error status, so if you do
./configure && make && make install
you get a compile-time error)
Debian testing users will need to install the separate plplot9-driver-xwin
package for the plots to actually work.
I shall begin testing GDL on some real-world code .... roll on contour!
And remember that a few years ago, the main implementation of S was S-Plus,
while R was a toy. R has now taken much of S-Plus's mindshare. OTOH, octave
has stagnated as a clone of a very old version of Matlab. Which will be the
main implementation of IDL five years' time: RSI's or GDL?

There have been open-source APL and J interpreters, but my impression is
that commercial interpreters are more widely used.
Octave wasn't just a clone, it introduced some ideas (structures) that
became part of real Matlab. Now Matlab has incorported ideas from octave
and many other extensions to the orginal language. R addressed
fundamental problems with S-Plus in student lab environments on multi-user
machines (it allowed you to limit the memory a user could allocate so one
user couldn't monopolize all the resources of a large server). I suspect
this meant that a large number of S-Plus users ported software to R for
use in courses and then found it suitable for "every day" use.
I started using R for statistical summaries and reports because it has
excellent support for dealing with missing values as well as the
statistical tools. Recently I've been doing more things in R because they
can be used by more people than if they are done in IDL, but GDL could
reverse that trend.
The grad students and recent PhD's I encounter generally have experience
with Matlab. A few have used R and a very few have used IDL. GDL would
need some compelling advantage to get it into eduational institutions
before it can have the level of success of R.
