SWI-Prolog, ADL, and Linux `gcc'?

[Bill Hogan <bhogan@rahul.net>]

  Hello.

  I am trying to build ADL on my Linux setup, using gcc 2.6.3.

  Everything appears to compile OK, but near the very end, where
SWI-Prolog is being linked, I get this:

--------------------------------- quote --------------------
Making SWI-Prolog 2.1.11 for i486-linux
[...]
gcc  -o pl pl-wam.o pl-save.o pl-stream.o pl-atom.o pl-arith.o

-ldl -lreadline -ltermcap -lm
ld: cannot open -ldl: No such file or directory

  Any help in solving this puzzle will be greatly appreciated.

  Thank you.

   Cheers,
