hi NAMD non-genius,

you are trying to run an obsolete beta version.
this is an incredibly pointless undertaking.

have you tried a proper release version or
if you must use a beta version at least the latest one?

your report is otherwise useless, since you
don't provide *any* information about the platform
(linux version, architecture, glibc version).

this looks like a shared linker issue. most likely your linux
has no backward compatibility libraries for ancient binaries.
