Define "support"?

To answer the above question, no, there is no way to resolve a missing
symbol problem without updating the appropriate fileset to a more
current level.

What is odd is why that symbol is used from a build on a TL04 system.
That symbol was not introduced until TL07, which implies that (a)
your builder has mixed things up on his/her build system, or (b) the
program wasn't build on TL04, it was built on a later level, which
means that you're out of luck. There is no forward compatibility.

To be precise, check your lslpp -l bos.rte.libpthreads output on both
the build system and execution system. The level on the build
system must be at or lower than the level on the execution system.
Otherwise, you're out of luck.
