problem (re)building modules

Hello:
	On a system running:

FreeBSD 12.0-CURRENT #0 r326723: Sat Dec  9 12:30:04 EST 2017  amd64

	I have 5 Perl modules that will not build.  They all fail with:

Socket.c: loadable library and perl binaries are mismatched (got handshake key 0xd200080, needed 0xdf00080)

	during the configure phase.
	I have rebuilt Perl(successfully), which is what Googling the
error message suggested as the fix.  Nothing changed.
	This is _way_ beyond my diagnostic skills.
	Help, please!


			Respectfully,


				Robert Huff
