I had the same problem, it is due to the changes from glibc2.1.1 to 2.1.2.
RSI released an updated version that fixes this, but you have to download
it off their site.
Moreover, _if_ you have the Motif libraries installed on your system, you
may want to relink the binaries to use them, instead of having them
hardwired in the binaries as they are by default. To do this, go into your
$IDL_DIR/bin/bin.linux directory, edit the Makefile you will find there
and build your own binary, linked against your Motif libraries and your
ncurses library (instead of termcap). Here is an excerpt from my own
modified Makefile:

LDFLAGS= -Wl,-rpath,. -lMesaGLU -lMesaGL -L/usr/X11R6/lib -lXm -lXp \
	-lXpm -lXext -lXt -lSM -lICE -lX11 -ldl -lncurses -lm \
	-L$(BINDIR) -lidl 

Check for the corresponding line in your system, edit it accordingly, make
idl.new and you have your brand new binary, dynamically linked.

_ANYWAY_ you need to first download the latest version of IDL from RSI.

Hope this helps...
