Using a statically linked Perl\, a program compiled with perlcc produces the following message\, if it requires Socket.pm​:

Can't load module Socket\, dynamic loading not available in this perl.   (You may need to build a new perl executable which either supports   dynamic loading or has the Socket module statically linked into it.)

Since Perl has Socket statically linked in\, at least the advice given in parentheses is wrong.

Sort of. perlcc works by compiling your program to an op tree structure\, dumping that out as a C data structure\, and then embedding a Perl interpreter which loads up that op tree and runs it. So the "this perl" it's talking about is not /usr/bin/perl (which *does* have Socket statically linked in) but the embedded Perl interpreter that perlcc has put into your compiled file\, which doesn't have support for dynamic loading.

This seems odd\, and if it's true\, it's a problem with B​::C\, which should write out an xs_init function which loads DynaLoader.
