   I believe that MATCH rule call actually returned an empty list no 
matter what your model command returned. Try writing it like this:

     if [ os.name ] = HPUX
     {
         if [ MATCH "^(9000/)" : [ SHELL "model" ] ]
         {
             type SHARED_LIB : sl : LIB ;
         }
     }
     else
     {
         type SHARED_LIB : so : LIB ;
     }

   I believe MATCH rule returns a list of strings found at locations 
marked using parentheses in your given regex. Since you gave no 
parenthised of the expression - nothing was getting returned.

   Also, I have not looked the the file you plan to insert this into, 
but could your if-logic perhaps be missing setting the .so extension for 
HP-UX machines that are not PA-RISC?

   Hope this helps.
