I'm trying to install gdb+dejagnu-20000419 on my Intel Pentium III running redhat linux 6.0. When I run ./configure with no arguments, there are no problems. If I type ./configure --prefix=/usr it doesn't finish the configure process, stopping with the message ... checking for Tk private headers... checking for tk.h... yes is installed checking for Itcl private headers. srcdir=.... configure: error: Can't find Itcl private headers Configure in /usr/local/src/gdb+dejagnu-20000419/gdb failed, exiting. Thanks, Jon Wilkening
