It's best to load the xspec module using
   require ("xspec");

'require' does the 'import' and then performs some additional
initialization and defines a number of useful slang functions.

If 'require' is not used, the xspec module will not be
completely initialized and probably will not work properly.

The best solution is to install libtermcap on your system.

I'm not sure why you're seeing this error. Presumably
libtermcap was present when isis was compiled, otherwise the
compilation ought to have failed.  Are you running isis on a
different machine that the one used to compile it?

Or is libtermcap installed in a non-standard location? If
that's the problem, then you might work around this by setting
the LD_LIBRARY_PATH environment variable appropriately, e.g
assuming DIR/libtermcap.so.2 exists, you could do:

  setenv LD_LIBRARY_PATH "${LD_LIBRARY_PATH}:DIR"

Installing libtermcap in a standard location is a better
solution, though.
