pkg conflict (perl5-5.20.2_4 with perl5.20-5.20.0_3) install subversion

[Christoph Kukulies]

I'm trying to install vmwaretools for FreeBSD 10.1 and in the course of 
that I'll have to build a patched kernel.
I'm advised to do pkg install subversion to get the kernel sources.

Doing this I'm getting a conflict:
[9/15] Installing perl5-5.20.2_4...
pkg: perl5-5.20.2_4 conflicts with perl5.20-5.20.0_3  (installs files 
into the same place).  Problematic file: /usr/local/bin/a2p

and bails out,

what to do?
