How to build TCL library?

    I am trying to build libpgtcl, in order to get pgaccess working.
    Infortunately I am having problems at configure time, as follows:

checking for tclConfig.sh... /opt/tcl-8.0/lib/tclConfig.sh
checking for tkConfig.sh... no
configure: warning: TK support disabled; Tk configuration script missing

    Sugestions please?

    company that can't stand for 1 bit of competition.
