I don't think you can use gpart on a slice of an MBR-partitioned disk. You can run "man gpart" if you didn't already; I didn't see anything to migrate an MBR partition table to GPT.
The older gpt, which NetBSD still uses, can migrate an MBR partition table to GPT. You could try Roderick Smith's gdisk http://www.rodsbooks.com/gdisk/ which is found, among other places, on the System Rescue CD http://sysrescccd.org/ also in sysutils/gdisk in FreeBSD ports tree. Rod Smith's gdisk can make a wider variety of partition types than gpt or gpart, and can also migrate an MBR partition table to GPT.
