All you need for a run-time "ns2 AquaSim" is aquasim-ns2_2.30-1ubuntu14_amd64.deb
I.e. that's what all run-time ns2 is about : The executable ns-name + the tcl libraries →
example → ns-allinone-2.35/{ lib/{libtcl*, tclConfig.sh, tcl8*/}, bin/tcsh8* }
The installed size is 9.1 MB for aquasim-ns2_2.30-1ubuntu14_amd64.deb →

----------------------------------------------------
For the best result AquaSim was built with CentOS 6.10, and the package aquasim-ns2_2.30-1ubuntu14_amd64.deb was created in Ubuntu 14.04 - amd64 from the "CentOS 6.10 AquaSim files".
-------------------------------------
......... And if you really want to build the files yourself ...........
Build example, CentOS 6.10 - x86_64 ......
# yum install gcc-c++ compat-gcc-34-c++ autoconf automake libtool libXmu-devel
$ mkdir AquaSim
$ cd AquaSim/
$ tar xvf [path-to)/Aqua-Sim-1.0.tgz
$ export CC=gcc34 CXX=g++34 && ./install
$ cd ns-2.30/
$ cp ns ns-aqua
# cp ns-aqua /usr/local/bin/
----------- Simulation, in aquasim-examples-01.20/ ---------
$ ns-aqua vbf_example_400.tcl
