The document accompanying the ISC DHCP product states that their
client does not work on Solaris.  It recommends using the native
client instead.  I'm sure it could be made to work, but somebody would
have to take on this project.  To initiate it, please file a bug
report.

Oracle Solaris 11 includes two DHCP servers, with a negative
dependancy so that you can't enable both of them at the same time.
Here's how they look:

The ISC DHCP server is in OI userland:

It likely hasn't been packaged yet.
