You're sure the base nmap executable binary bits are the same so
it's something specific to the failing machine, yes?

Sooo, some preliminary shots in the dark:

 - Machines same distro?  Same architecture?  i686 vs. x86_64?

 - PATH and LD_LIBRARY_PATH are correct?  ie. you're actually
   loading the intended binary and pulling in the intended libs?

 - execute ldd against the nmap executable on all machines
   and compare results.

...etc, etc...
