I see that your xspec_lmodels directory mentions "i686", which
normally suggests a 32-bit build, while your HEADAS path
mentions "x86_64", which normally means a 64-bit build.

Try the following:

  % file /usr/local/isis/isis/1.6.2/lib/modules/xspec-module.so
  % file /usr/local/xspec_lmodels/i686/libxspec_lmodels.so

What output do those two commands produce?
I'm wondering if the first shared library is 64-bit and the
second is 32-bit.  If so, then that's the problem -- the
local model shared library should be compiled as 64-bit,
the same as isis and xspec.

If both are 64-bit, then please try the following:
Please run isis like so:

   setenv LMODDIR /usr/local/xspec_lmodels/i686
   strace -o /tmp/xxx.log isis 

and then at the isis prompt, do:
   isis> require ("xspec");
   isis> exit;

Then please send me the file /tmp/xxx.log

Thanks,
