Suggest : Use your {un-patched / unmodified / stock} executable /usr/local/bin/ns-orig :
Then all default simulations can be run ...
Note : You can have as many ns-allinone-2 as you want, installed at the same time.
About the "clone aomdv" : May be you got it to work with some simulation(s) ?
.... Don't expect a modified ns2 to work with default simulations.
( Though some (a few) added protocols are harmless.)

I solved the above error but still when I run .tcl file containing ad hoc node configuration, it says
can't read "numifs": no such variable ....
i use ns adhoc.tcl
can't read "numifs": no such variable ....
i use ns adhoc.tcl

"adhoc.tcl" : Please attach the file, renamed to a new unique name.

There are some typos in the adhoc.tcl, I attached.
The new edited version adhoc-17.tcl is included in manet-examples-4.tar.gz

Why care ? You can have a hundred times ns-allinone-2.35 installed at the same time.
Just keep all the executable 'ns-any-name' in /usr/local/bin/ .
/usr/local/bin/{ ns-orig, ns235-dir-antenna, etc. etc.}
... And no *PATH text can be added to .bashrc : Never required.
However, it is possible to remove a patch :
