I'm using a Slackware distribution, so it won't be exactly the
same as the RedHat distribution; but, I've successfully compiled
BLT and libtclobjc without the statically linkable tcl/tk.  But,
you may have to do a 

  % ldconfig

after installing new sharable libraries. You should be able to tell
if your ld.so.conf is wired properly by doing:

seamus:~$ less /etc/ld.so.conf
/lib
/usr/lib
/usr/local/lib
/usr/X11R6/lib
/usr/i486-linux/lib
/usr/i486-linuxaout/lib
/usr/openwin/lib

(the directories will probably be different on your machine),
and making sure that libtcl.so exists in one of those directories.

Mine just happens to look like:

seamus:~$ ls -l /usr/lib/libtcl*
lrwxrwxrwx   1 root     root           11 Jan  8 12:36 /usr/lib/libtcl.so -> 
libtcl.so.1*
lrwxrwxrwx   1 root     root           15 Jan  8 12:36 /usr/lib/libtcl.so.1 -> 
libtcl.so.1.7.5*
-r-xr-xr-x   1 root     root       260031 Apr 27  1996 /usr/lib/libtcl.so.1.7.5*

and

seamus:~$ ls -l /usr/lib/libtk* 
lrwxrwxrwx   1 root     root           10 Jan  8 12:36 /usr/lib/libtk.so -> 
libtk.so.1*
lrwxrwxrwx   1 root     root           14 Jan  8 12:36 /usr/lib/libtk.so.1 -> 
libtk.so.1.4.1*
-r-xr-xr-x   1 root     root       543966 Apr 27  1996 /usr/lib/libtk.so.1.4.1*


If the directory in which your libtcl.so -> libtcl.so.1 -> libtcl.so.1.7.5
doesn't reside in the ld.so.conf file, you can edit that file then
run ldconfig.

BTW, Swarm will work with Tcl 7.6/Tk 4.2 if you're interested (you
just have to change one function call in BLT) and Barry found a 
fix for the Raster bug, also.
