>Description:

libBLT24.so has no ldd dependencies on tcl or tk.

$ ldd /usr/local/lib/libBLT24.so.3
/usr/local/lib/libBLT24.so.3:

This causes a problem in some environment, say py-tkinter, which is a Tk wrapper
for Python.

>How-To-Repeat:
	
The operation equivalent to "package require BLT" in Tcl/Tk fails.
libBLT24.so can't resolve TclpAlloc in libtcl84.so because it has no dependency.

$ python
>Fix:

The patch below is originally Bill Barnard posted to SourceForge.
http://sourceforge.net/tracker/index.php?func=detail&aid=1470209&group_id=18616&atid=318616
 
This makes libBTL24.so built with valid dependencies.
