first off, depending on the kind of analysis you want to do,
using the bigdcd script might help with he memory issue.
second, yes you can compile VMD without graphics, but
if it is just about getting it to run on a cluster node, you can
just copy the libraries that are missing on the compute node
into a directory that is readable on that node and then point
the LD_LIBRARY_PATH environment variable to it.
you can find out what you need but running the ldd comand
on the VMD executable (not the vmd script but the real one
that has the name vmd_<ARCH>. example:
