I've used binary modules compiled with gcc + a gcc-built perl on ActiveState perl. I don't remember specifically trying ActiveState-built modules on my gcc-built perl - but I've not encountered any problems.

I generally use my gcc perl to compile modules that can be installed by other users in the the department that have a standard, supported desktop installation of ActiveState perl. Off the top of my head some of the binary modules that I've built and used in this way are:

• XML::LibXML (+ libxml2)
• XML::LibXSLT (+libxslt)
• Wx
• Devel::Size
• PAR
• Inline

You can also compile binary modules with gcc and ActiveState perl, using ExtUtils::FakeConfig.
