Yes.  Forget the "cross platform" stuff - it probably refers to the fact
that a .par archive may contain XS Perl modules for different architectures
or operating systems. But there's no support to build such a "fat" archive
and the executables created by pp are architecture or OS specific in any
case.

So in short: if you want to generate binaries for Windows and Linux, you
must build them twice. Which also means that you first must have all the
modules that your script needs in both worlds as well as PAR::Packer
itself.
