XS or SWIG, you can find an introduction to both in the Advanced Perl
Programming book.
For a wonderfull series of XS articles see:
http://www.perlmonth.com/columns/modules/modules.html?issue=6
http://www.perlmonth.com/columns/modules/modules.html?issue=7
http://www.perlmonth.com/columns/modules/modules.html?issue=8
http://www.perlmonth.com/columns/modules/modules.html?issue=9
http://www.perlmonth.com/columns/modules/modules.html?issue=10
And of course: perldoc perl, which gives:
perlembed Perl ways to embed perl in your C or C++ application
perlapio Perl internal IO abstraction interface
perlxs Perl XS application programming interface
perlxstut Perl XS tutorial
perlguts Perl internal functions for those doing extensions
