Well, same mystery, different library.

The options that torque is passing to libtool are what I would expect.

So libtool is expanding -ljob to /usr/lib64/libjob.so and adding -lcap -lpam. I
don't know why.

Can you send me your generated config.log and libtool? I'll take a look but I
suspect this is something on your system that is adding those libs and not
something that we can control in torque.

I suspect that your libjob.so requires libcap and libpam and libtool is just
doing the right thing.

You might edit your generated libtool and remove "-lcap -lpam" and see what

Right, because our PAM support has nothing to do with this.
