Compile fails for ports/x11-toolkits/tk84 (fix attached)

[Nick Triantos]

Hi,

I'm running FreeBSD 4.10.  When I try to build ports/x11-toolkits/tk84, 
I get a pile of compiler errors.  Google shows others are also seeing 
the same problem.

To fix this, I manually hacked 
/usr/ports/x11-toolkits/tk84/work/tk8.4.6/unix/Makefile, and changed 
line 86 from:

TCL_GENERIC_DIR         = /tmp/a/ports/lang/tcl84/work/tcl8.4.6/generic

to

TCL_GENERIC_DIR         = /usr/ports/lang/tcl84/work/tcl8.4.6/generic

I don't understand enough about the build system to see how it assigned 
that variable based on Makefile.in, but I think someone more familiar 
with the build process should try to fix this correctly, if they can.

thanks!
