OK ... I rebuilt without --with-tm= and as predicted my test case
runs (I left the IB flags in). I then ran a job with just:
on 16 nodes and that also worked. I know that 1.4.1 works although
it was build pointing into the old PBS Pro version tree explicitly. I
have checked and rechecked the environmental variables and everything
else that could lead to some mixed-up version cross referencing.
I am tempted to build 1.4.2 with the explicit -with-tm= version path
instead of using the symlink to default, but I cannot think of a logical
reason why that should do anything.
I have also reported this to the PBS Pro support folks.

I'd say both.
But it would be quite surprising if tm_init() it wholly broken -- it's the very first function that has to be invoked.
I'm not a PBS user, so I don't know/remember the PBS commands offhand, but I have a dim recollection of a few PBS-provided TM-using tools (pbsdsh or somesuch?). You might want to try those, too, and see if they work/fail.
If it really is a problem, I'm guessing it'll be a compiler/linker issue somehow... (e.g., how we're compiling/linking is not matching the compilation/linker style of the TM library) That's a SWAG. :-)
