If you really want to build it for yourself, you can do as your system
offered and install the compiler package in question. Once you have a
working compiler installed, then you'll be able to compile software
from source.

It might be much easier for you to use the pre-built NAMD binaries,
either for Windows or for Linux. They are linked from

http://www.ks.uiuc.edu/Development/Download/download.cgi?PackageName=NAMD

More generally, if you encounter an issue with NAMD, the developers
have lots of great support resources listed on their web site:

Finally, when getting help from members of a mailing list, please
address the list on all responses, so that the community benefits from
the conversation.
