perl version error

I'm trying to build biber-2.3 as a packed perl archive for upstream TeX 
Live. I'm getting the following error:
/tmp/parl4zru: Perl lib version (5.22.1) doesn't match executable 'perl' 
version (5.22.0) at /usr/lib/perl5/5.22/x86_64-cygwin-threads/Config.pm 
line 62.

/usr/bin/pp: Failed to extract a parl from 'PAR::StrippedPARL::Static' 
to file '/tmp/parlVkntMjx.exe' at 
/usr/lib/perl5/vendor_perl/5.22/PAR/Packer.pm line 1158, <DATA> line 1.
Can any of the perl experts explain what might cause this? Might it 
mean that Cygwin's perl-PAR-Packer needs to be updated for perl 5.22.1?
TIA.
