OK I think the problem is you are using mmap in ZM and for some reason 
mythzmserver has been compiled without mmap support. The mmap support is 
conditionally compiled based on the value _POSIX_MAPPED_FILES which 
according to the mmap man page should be defined in unistd.h on my 
system it is actually defined in /usr/include/bits/posix_opt.h.

Wonder if we just need to add an include for unistd.h? Try adding 
#include <unistd.h> to the top of zmserver.cpp.
