The MPC format should always be part of the build.  However, it seems 
that the behavior is as if the MAGICK_CODER_STABILITY environment 
variable is set to PRIMARY to filter out all of the formats with a 
stability level less than PRIMARY.

Try setting MAGICK_CODER_STABILITY=UNSTABLE.  I am not totally sure 
why the MPC format is marked this way but suspect it could be due to 
concern over possible unintended use.  It has been marked this way 
since the notion of coder stability was added back in 2008.

If this is not your case, then check if something about your build or 
the OS configuration is keeping getenv() from working normally.
