Several things:

1. This file is completely messed up - it is missing a bunch of random 
parameters not just the ones that should have changed.  It has no V, W, 
time, baseline, freqsel, source, etc.  Your problem is then this data 
set and may not involve any issues with aips version.  I don't thing 
that GMRT compiles AIPS itself - the 31DEC13 version had a bunch of 
issues in doing that (which have been fixed).

2. 31DEC14 is available from rsync - the web page may tell you it is not 
but ftp.aoc.nrao.edu/pub/software/aips/31DEC14 will let you copy 
install.pl and then perl install.pl -n with that copy should work.
