> Because p5-libapreq2 won't build with perl5.18 -- see http://trac.macports.org/ticket/28831 -- and because perl5.18 is currently my default version of perl5, I need to try again but now with perl5.16. How?
> 
> I tried first "sudo port select perl5 perl5.16" (and same thing with just "perl" instead of "perl5") but get error "The specified group 'perl5' does not exist."
> 
> Next attempt was to uninstall perl5.18:
> 
>  $ sudo port uninstall perl5.18
> --->  Unable to uninstall perl5.18 @5.18.2_0, the following ports depend on it:
> --->  	perl5 @5.12.4_0+perl5_18
> Error: org.macports.uninstall for port perl5.18 returned: Please uninstall the ports that depend on perl5.18 first.
> Please see the log file for port perl5.18 for details:

> Unfortunately, trying to uninstall perl5 @5.12.4_0+perl5_18 won't go through because I have a large number of other ports that depend upon perl4.12:
