GPT fdisk on illumos

Is there an alternative to the illumos native fdisk? Yes, for example, GPT fdisk from Rod Smith. It includes the gdisk, cgdisk, sgdisk, and fixparts programs. Site mentions only usage on Linux, FreeBSD, Mac OS X and Windows, but it is possible that GPT fdisk may be suitable on illumos-based distributions. It requires popt library (OmniOS contains it) and latest version built with no problems, except for a small fix for ncurses.
