Re: libcudart.so.4 error

This may be your problem:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/vmd/libcudart.so.4

You append the libcudart.so.4 path at the end of $LD_LIBRARY_PATH and NAMD
uses the first instance it finds (the ones that you previously appended).
Try this one this time:

export LD_LIBRARY_PATH=$NAMD_HOME:$LD_LIBRARY_PATH
