The pkgIndex.tcl file that is installed by the Windows releases

    blt24v-for-tcl80.exe
    blt24v-for-tcl81.exe
    blt24v-for-tcl82.exe
    blt24v-for-tcl83.exe

has two bogus lines.

    set version "%VERSION%"
    set libdir "%LIB_DIR%"

This should be replaces by

    set version "2.4"

Thanks to Stephen Cohen for the bug report.

This will be fixed in the 2.4w release out next week end (Nov 10).  Please let me know about any other bugs so that they can be put in the 2.4w release.
