BTW, keep in mind that your usage of LIBS will use each array member as a complete set of arguments to ld, which means that if you had the '-ldrmaa' as the last array member you would have never even have gotten that warning. If all those libraries are mandatory you need to pass them as a single array member. Quoting the pod: LIBS An anonymous array of alternative library specifications to be searched for (in order) until at least one library is found. In any event, setting LD_LIBRARY_PATH won't override the search path when testing for libraries, you'll need to add it to LIBS as well: LIBS => ["-L$SGE_ROOT/lib/sol-sparc -ldrmaa", ...] --Arthur Corliss Bolverk's Lair -- http://arthur.corlissfamily.org/ Digital Mages -- http://www.digitalmages.com/ "Live Free or Die, the Only Way to Live" -- NH State Motto
