Sure thing, except that it's written in Haskell, so one has to either use
the binary package or download and/or build rather heavy environment to
"make install" it.

It also reports slightly different (and scarcer) values, e.g. on this AMD
A8-5550M of mine:

  $ cpuid2cpuflags
  CPU_FLAGS_X86: aes avx f16c fma3 fma4 mmx mmxext pclmul popcnt
  sse sse2 sse3 sse4_1 sse4_2 sse4a ssse3 xop

  $ /usr/local/bin/cputype -f
  xop avx sse42 sse41 ssse3 sse4a sse3 amd64 sse2 sse mmx

That said, I think both tools can be useful and have their place in the
ports tree. :-)
