[GRASS5] Tcl/Tk config on Linux??

[Chris G. Nicholas]

greetings - I did a fresh CVS checkout of the grass sources, and am trying to *just* get past the "configure" script  :-( 

I downloaded/built the Tck/Tk source packages, "cd unix; configure;make; makeinstall" -- no problems. Everything appears to have installed just fine in /usr/local .

But I keep getting "Unable to locate Tk includes"... :-(

And the #$%^ing include files are there!!

Before mercilessly hacking the configure script, thought I should ask this alias...

ideas/suggestions welcomed!
thanks!
Chris
