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:

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.

% package require tls
couldn't load file "/srv/tcl/lib/tls1.8.0/libtcl9tls1.8.0.so": /srv/tcl/lib/tls1.8.0/libtcl9tls1.8.0.so: Undefined symbol "Tls_DigestCommands"

Please use the tls-1.8 branch until I merge it with trunk. It has all of the
latest fixes including tclconfig, makefile updates, etc.

I've tested compatibility with FreeBSD and can verify that trunk now works without issue on FreeBSD 14.1.
There were a few issues in the makefile related to FreeBSD using sh rather than bash.
