Description: Patch fixes loading the libBLT library from
    [package require BLT]. Specifically, it provides correct version
    BLT_PATCH_LEVEL and prevents loading the library twice (once
    by its real name and onr more time by a symlink if the blt-dev
    package is installed). Also, it skips initializing widget bindings
    if Tk isn't present.
