poudriere upgade perl in jail

[Bas Smeelen]

I have poudriere setup on a server to compile packages for my old 
laptop, mini, and some friends laptops and it works great.

How can I upgrade the perl version of the poudriere jail to perl-5.16, 
it is now perl-5.14?

I tried startied the jail with poudriere jail -s -j and then try jail 
command=portmaster -o lang/perl5.16 lang/perl5.14 but can't get this to 
work.

Should I just wipe the jail, then recreate and first build perl5.16 in 
it before building the other packages?

I have read the man pages for poudriere and jail and searched the web 
for this, but can't get to the right solution.

Thanks in advance.
