Perl plugin by Verliba

Your perl must be compiled with -Duseshrplib option which means shared library support in order to use the
perl plugin. On Debian you can install perl-devel, but on slackware there is no perl-devel package.
I compiled my own version, and works well.

Install Verlihub before the perl plugin:
go to verlihub project, make it, and "make install", Note, you can profit of the ./configure --prefix /some/folder
which tells you where should be verlihub installed.
After making verlihub you'll find a file called verlihub_config in it's folder (which is not installed now .. to verify)
you can copy it anywhere into the reach of PATH, so that typing verlihub_config would execute it..
When it's done, you can run ./configure of this script

Using plugins in verlihub:
verlihub has two mechanisms for the plugins
1/ the .verlihub/plugins folder (which you may wanna create)
2/ !plugin !pluout !plugreload !pluglist all commands

the plugin can be found (after running 'make') in the src/.libs folder

* if you wanna load plugin automaticaly on startup of verlihub, put a file called (in this case) "libstats_pi.so" 
which is the plugin itself. verlihub searches for files called .verlihub/plugins/*.so and tries to load them

!pluglist all
and you will see it there

!plugin relative/path/filename
!plugout PluginName1.0
!plugreload PluginName1.0
