This may or may not work (it passes the "microperl -e 'use CGI'" test):

build microperl and load it on your gumstix. now transfer the following 
files/directories from your microperl buildroot to a "central" directory 
like /usr/lib/perl5 on your gumstix:

Carp/
Carp.pm
CGI/
CGI.pm
constant.pm
Exporter/
Exporter.pm
overload.pm
strict.pm
vars.pm
warnings/
warnings.pm

You may have to fiddle with @INC to add this directory of code so 
microperl picks it up.

Note: because you can delay the loading of modules beyond the compile 
phase (through the do {} and require {} constructs), you may get warnings 
about additional modules needed to run your code

You may also find CGI doesn't work exactly as planned because microperl 
is, well, micro and a lot of the OS-specific stuff is stripped out. you'll 
have to experiment to find what works and what doesn't.

Modules that require compilation of C code (XS modules) won't work with 
microperl since the dynaloader isn't built in to it.

The doc for CGI is: http://perldoc.perl.org/CGI.html

A good book is "CGI Programming with Perl". Otherwise, there is Google.
