Ok, seems sane enough.  I do wonder what /usr/local/openjdk6 is though.
That may cause problems further down the line.

You don't seem to be using the latest; that would be 1.11.1.  If you want
to get the end result into IcedTea, you may be better working with the
Mercurial version:

http://icedtea.classpath.org/hg/icedtea6

Then you can see what changes have been made via hg status/diff.

The patch issue is rather odd.  Are you rerunning a build over an existing
OpenJDK tree as Andrew said?  What I'd recommend for ease of debugging is
to build in a separate directory:

$ mkdir icedtea6-build
$ cd icedtea6-build
$ ../icedtea6-1.11.1/configure <params>

which you can then just rm -rf if it doesn't work.  make clean works too,
but this is usually quicker and more guaranteed to work.

You mention something about having to fix up patches?  Can you give more
details?

You're more than welcome to try and don't get me wrong - I love to see
FreeBSD support for OpenJDK6. I just worry that it'll be a lot of work
for something that may be decommissioned a few months after you finish.
There won't be *BSD support for a lot of things in OpenJDK6 as it stands,
so it'll need backporting from 7.  That may have been feasible a few years
ago, but today there doesn't seem much point.
