gscan2pdf Perl errors

[Glenn and Sheryal]

I am getting the following error when I attempt to run gscan2pdf on a
newly built system.  The port was installed using portinstall.  

Can't locate Sys/SigAction.pm in @INC (@INC
contains: /usr/local/lib/perl5/5.8.9/BSDPAN /usr/local/lib/perl5/site_perl/5.8.9/mach /usr/local/lib/perl5/site_perl/5.8.9 /usr/local/lib/perl5/5.8.9/mach /usr/local/lib/perl5/5.8.9 .) at /usr/local/lib/perl5/site_perl/5.8.9/mach/forks/signals.pm line 10.

BEGIN failed--compilation aborted at /usr/local/bin/gscan2pdf line 105.
Undefined subroutine &threads::_END called at (eval 1) line 1.
END failed--call queue aborted.

So I tried to portinstall devel/p5-Sys-SigAction and although it
reported that it was looking good it failed to compile.  What am I doing
wrong?
