It appears that the latest trunk is uncompliable on FreeBSD. It compiles, makes and make install fails missing tclconfig. I had to copy this from another package directory where it existed.

**Error**

    /bin/sh: cannot open ./tclconfig/install-sh: No such file or directory
    *** Error code 127
    Stop.
    make: stopped making "install" in /srv/~scrap/tcltls/tcltls-bc6ff74449

this can be fixed by copying ./tclconfig from tcltls-1505883e4a

     cp -R ../tcltls-1505883e4a/tclconfig/ ./tclconfig/
     make install
     Installing header files in /srv/tcl/include
     Installing ./generic/tls.h

and then is loadable.

    % package require tls
    1.8.0

Additional branches I've tried:

    tls-1.8
    tcltls-1505883e4a

However, if I copy Makefile and configure from bc6ff744494d3b41 in to tcltls-1505883e4a -- this enables compilation and installable but not loadable within TCL9

    % package require tls
    invalid command name "cipher_is_aead"

Doesn't work ~ requires copying of Makefile and Configure as above.
