Well, I need to install ns2 (network simulator 2) which requires
tcl8.4.5. tcl installation however does not work. configure/make
scripts seems to be crafted for older versions of bash. I came to know
that 3.1 version is very fussy since a few obvious mistakes in scripts
were ignored by older bash versions but 3.1 gave warning and stopped.

BTW, I came across Ubuntu package search toolbar in firefox and found
older bash versions from Hoary, Warty and Breezy. Do you think it is 
safe to install an older version. Or will it be a big mess?

bash-static (2.05b-15ubuntu5) only depends upon locales (>= 2.3.2). Do I
need to remove the current version or can both bash version coexist
peacefully just like multiple gcc versions on one system?

Any ideas?
