there is a need to tweak the Perl source, if you really want perl executable with any extension to be linked statically into the main executable.

I was able to statically link into perl58.dll Tcl::Tk and some required for me modules. But you need some kind of linking set and some developed approach if you're going to gather some (unknown) extensions into the main exe.

PS.(keep in mind, this is not PAR approach, where huge ZIP is unpacked into %TEMP%)
