In case any of you are wondering if it builds, it does!! I just built it with the binary ghc, ghc-6.6-i386-unknown-linux.tar.bz2, parrot-0.4.6, and the prerequisite modules...

# from the install file
v6-pugs  needs the CPAN modules               
Devel::Caller, 
Module::Compile 
and Pugs::Compiler::Rule. 
The first one is dependent on 
Module::Build with C_support, 
so install ExtUtils::CBuilder and              
ExtUtils::ParseXS first. 

Satisfy all with one command:                                    
                                                                      
+                    
$ sudo cpan -fi ExtUtils::CBuilder ExtUtils::ParseXS Module::Build \  
+                
Devel::Caller Module::Compile Pugs::Compiler::Rule

It took a half hour to build, on my 2ghz system, and /usr/bin/pugs was over 10.2 megs stripped. It looks like they are on the way. :-)
