Hi Pallab,

Yeah... The precompiled versions are useless for their python support nowadays, and if you are really keen you should just compile VMD yourself. On Linux, the easiest to read instructions for compiling VMD from source were made by Robin Betz: http://robinbetz.com/blog/2015/01/08/compiling-vmd-with-python-support/. Debian packages also exist (just ask!), but are not tested on a wide number of configurations.

Please read the error message:

Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]

and the relevant section of the VMD user's guide:

Pre-compiled VMD binaries currently use Python version 2.5. The current VMD source code has been tested to compile with Python versions 2.4 to 2.6 on a few platforms. User contributed VMD rpm or deb packages can be thus be compiled against any of those versions.
