I can't find this message in the archive so am not sure what I said could
you please send me the link.

This to me sounds like the library versions are different in some way.
Either you are running interactively on one machine which doesn't exactly
match the machine that the code runs on when you use PBS. Alternatively the
environment may be different when using PBS so that PATH and LD_LIBRARY_PATH
is different and thus referencing different library versions.

You could also try using static linking (add -static to the load line in
config.h) I.e.

Although on an Altix you may not be able to successfully link statically due
to licensing issues with the math libraries but it is worth a try.

If none of this works then please send more details such as OS version,
environment both when using PBS etc.

All the best
