Mountain Lion/Xcode/Macports upgrade failure

[Jason]

All,

Yes, I know this is a FAQ.  I've read them, I've tried them.  No luck.

I have a MBP that was running Lion, Xcode, and up-to-date macports.  I
then made the mistake of upgrading to Mountain Lion.  My openvpn still
worked, but gkrellm/X11 would exit with error code 1.  So, thinking
gentoo-like, I'll do 'port upgrade outdated'.

I'll be honest, I don't remember what the error was, I do know the good
idea of the moment was to install the latest Xcode.  This went fine.
Then I got the 'unable to find make' problem.  A bunch of sites advised
going into Xcode -> Preferences -> Downloads and pulling in Command Line
Utils.  But it wouldn't show for me.  I've rebooted, reinstalled,
xcode-switch'd, to no avail.

So my logic goes, it must already be installed.  After fiddling with the
PATH, (and finding make and friends in
/Applications/Xcode.app/.../usr/bin), I added
/Applications/Xcode.app/.../usr/bin and
/Applications/Xcode.bin/.../Tools to binpath in
/opt/local/etc/macports/macports.conf.

And this is where the trouble started.  I decided to run 'sudo port
upgrade outdated' A quick warning about gperf not being found and bam,
things were broken.  I interrupted the update, but it was too late.
After trying a few other things which didn't work, I decided to blow out
macports (and everything it installed) and start over.

I still have the problem.  I'm starting with a simple 'sudo port install
gkrellm' and I get:

I'm at a loss.  I've been using Linux for years, but am new to OSX.  Any
help would be appreciated.

thx,
