maxima startup error message (libgmp)

[Charles Blair <c-blair@uiuc.edu>]

   I thought I had installed maxima sucessfully from the
etch (testing) distribution, but typing "maxima" from an xterm gave:

error while loading shared libraries:
libgmp.so.3: cannot open shared object file: No such file or directory

   Can this be fixed by downloading libgmp.deb (or similar name)
and typing

dpkg --install libgmp.deb

or is something more subtle needed?
