[ns] configure --with-tcldebug problems

[Robin Poss <robin@anise.ee.cornell.edu>]

Hello!
I have a very classical allinone installation, I checked the problems 
page at  http://mash.cs.berkeley.edu/ns/ns-problems.html#ns-2.1b6,
and when I run  configure --with-tcldebug from  
/root/ns-allinone-2.1b6/ns-2.1b6 I get:

[snip]
checking for otcl.h... no
checking for libotcl1.0a4... no
configure: error: otcl is required but could not be completely found.  

So I added options:
 ./configure --with-tcldebug --with-otcl=/root/ns-allinone-2.1b6/otcl-1.0a5 --with-TclCL=/root/ns-allinone-2.1b6/tclcl-1.0b9  
but I still get:

checking for libotcl1.0a4... -L/root/ns-allinone-2.1b6/otcl-1.0a5 -lotcl
checking for tclcl.h... no
checking for libtclcl1.0b8... no
checking for tcl2c++... no
configure: error: TclCL is required but could not be completely found.  

I checked  and I don't have libtclcl1.0b8 on my system. How could I get it and
what should I do with it once I have it?

Any other suggestions on how to get configure --with-tcldebug to work?

Thanks,
