plperl question: how to specifiy perl version?

[Dave Thompson <dthompso@xxxxxxxxxxxxxxxxx>]

Hi,

I setup a plperl handler in Postgres 8.1 running under Solaris. The 
machine has multiple versions of Perl installed, and plperl is not using 
the correct Perl binary. How do I set which Perl binary plperl should use?

Thanks
