Hi Cyril!

Sorry, I think your "patch" tag is a bit to fast; at least I'm not yet
sure if it's ppracers fault, nor if what's the proper way to fix it.

I'm not yet sure if it's ppracer configure beeing wrong.  It's sourcing
/usr/lib/tcl8.4/tclConfig.sh to get those variables, and the script
shipped with tcl8.4-dev_8.4.12-1.1 did contain TCL_INC_DIR.  The one
shipped with tcl8.4-dev_8.4.15-1 does not.

So I'm wondering, why Tcls behaviour changed?

Lucas, have there been other Tcl related FTBFS?


BTW:  We don't need to patch configure, Makefiles or configure.in;
calling configure with
"--with-tcl-inc=/usr/include/tcl8.4/tcl-private/generic" works, too.
But before uploading with that change, I would really like to hear input
from tcl maintainers.


Yours sincerely,
  Alexander
