Packages which used to use the debian-specific hack TCL_INC_DIR from tclConfig.sh to find the tcl (or tk) headers should be modified to use the new patented upstream TCL_INCLUDE_SPEC variable instead. TCL_INCLUDE_SPEC is a little different than TCL_INC_DIR -- it includes a "-I" in front of the path, so if you were using "-I$TCL_INC_DIR", you should change it to just "$TCL_INCLUDE_SPEC". If you were doing something with TCL_INC_DIR that isn't compatible with have "-I" at the front, LET US KNOW! TCL_INC_DIR is removed from tcl8.5 and wasn't introduced in tcl8.6. So, anything still using TCL_INC_DIR will *break* if you want to build it with Tcl/Tk 8.6! If you have a problem with that, LET US KNOW, as soon as possible! cheers Chris Waters, 8 Dec 2002, Sergei Golovan, 26 Jun 2008
