The problem was that liblmodel.so introduced a symbol that is
normally provided by xspec, but that is not used in computing
the swind1 model.

When isis tried to load liblmodel.so, this symbol was undefined
and the load failed. To satisfy the dynamic linker, the xspec
module now provides a stub definition for this symbol
(Tcl_PkgProvide).  That solves the problem.

This fix will be included in the next isis release.
