Header checks don't simply check that the file exists; they attempt to
preprocess a test program which consists of a #include statement for
the header in question (in this case "#include <tk.h>"); if the
preprocessor produces any error/warning messages, the check fails.

tk.h depends upon the X headers, as well as tcl.h. So if there are any
problems with the X headers, the check will fail. Note that "problems"
includes anything that results in a warning, not just errors.

Examine config.log for any clues.
