This is where there are limitations to PAR. You are quite right about XS
code not being cross platform. PAR does have a "multi-arch" mode which
includes a way to include platform dependent code for multiple
platforms, much like Apple has binaries that run on PPC and Intel.
However, there is no magic solution to generating platform independent
binaries here. To add in the code for target platform, you are expected
to run PAR /there/ as well.
In the example, it just mentions "src.pl".
This part of the documentation is not clear. Is there is really a simple
PAR command to run on the target server, or would you essentially have
to copy the whole application and its dependencies over the new server
to create the PAR file? (Which sort of defeats the purpose...)

Generally, Yes. I've done it. But in this case, No, because FreeBSD
couldn't find the "libc.so.6" file in needed. It existed on the system
under "/usr/compat/linux", but wasn't found there.
