I've been using a pair of small, very old C programs for years:
base64-decode.c and base64-encode.c; they date from 2000 (!).  Have not
used them on 12.04 yet; but they work well on both RedHat and Ubuntu
10.04. 

You're more than welcome to them if you want; I just put a copy of both
here: 

  http://www.cv.nrao.edu/~pmurphy/base64-decode.c
  http://www.cv.nrao.edu/~pmurphy/base64-encode.c

They're very generic C and should compile easily with gcc.

Does "cat filename | munpack" work?  I assume that's (similar to) the
mode in which vm calls the external programs.

HTH.

       All your sanity and wit, they will all vanish, I promise;
       It's just a matter of time.
