You're not having any luck with PLs at all, are you?

I seriously doubt that that's a correct value for TCLSH; the variable is
supposed to reference the tclsh executable, not a directory.

Comparing that to relevant entries in pl/tcl/Makefile,

tclwithver = $(subst -l,,$(filter -l%, $(TCL_LIB_SPEC)))
TCLDLL = $(dir $(TCLSH))/$(tclwithver).dll

$(tclwithver).def: $(TCLDLL)
pexports $^ > $@

it seems pretty clear that tclwithver is being set to the empty string,
which suggests that TCL_LIB_SPEC is empty or doesn't contain any word
starting with "-l". You could look into src/Makefile.global to see
what value configure has obtained for TCL_LIB_SPEC. AFAICT, it gets
that value verbatim from tclConfig.sh, so this suggests something
messed-up about your Tcl installation. Or maybe the bad value for
TCLSH is somehow causing this, though I'm not sure how.
