First off, are you using GSL version 1.2?  That's from 2002.  Use GSL
1.15 from ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz.

Secondly, what are the compilation and link lines appearing above the
linking error message that you see?

For example, when I run 'make' within the siman directory, I see
messages beginning like
   /bin/sh ../libtool --tag=CC   --mode=compile gcc ...
   libtool: compile:  gcc ...
   /bin/sh ../libtool --tag=CC   --mode=link gcc  ...
   libtool: link: ar ...
What do you see?  I suspect that what you see is missing a '-lm' flag
which is why you're getting undefined reference errors to math
routines like atan and exp.
