hm.  i had no idea.  never used the 1.x branch

libapreq is mostly an apache module that provides a c library, not a  
perl one.  it ships with / is popular for the Perl glue it provides.
i *believe* its being mostly split and migrated into apache core and  
mp2, but i could be wrong.  someone else here will chime in,

you don't need libapreq to get to the post data.  there are a ton of  
modules that do that in pure perl (like the cgi series, and others )

libapreq / Apache2::Request just does it fastest -- and handles it as  
$r->param

i think it works out of the box on freebsd only ( thanks AGAIN to  
Philip )

if you use ubuntu, you can get it to work off the global (or whatever  
its called ) ports tree , just by switching sources for apt-get.

its a damn nightmare to do in suse/redhat/debian -- you're better off  
building from source on those platforms.

its poorly maintained in most ports trees though.  usually its only  
on the distros that a big site that runs it uses.  apache2/mod_perl2/ 
libapreq2 is an often forgotten system.
i think its half because everyone is hyped up over php/rails, and  
half that its geared for dedicated servers (not shared ones).  yet  
its still one of the fastest and most stable frameworks around (which  
is why smart people use it).
