I have successfully built MacVim many times in the past from source.
I am no longer able to do so.
When I run the MacVim.app that I've built, it starts up,
but no Vim window opens.
If I do ⌘N, nothing happens.
When I do ⌘Q, I get a dialog telling me that
there are two open windows in MacVim.
Removing my ~/.vim and ~/.vimrc
(because I don't know how to run -u NONE),
doesn't help.
I'm running Xcode 4.5 (4G182) on OS X 10.7.5 on one machine,
and Xcode 4.5.1 (4G1004) on 10.7.5 on another.
I've installed the latest command-line tools via
Xcode's Preferences > Downloads.
I tried running MacVim.app under the Xcode debugger.
Once, after pausing at a breakpoint in main() for a while,
I actually saw the Vim window open.
Unfortunately, I know nothing about Xcode, Objective-C, Cocoa,
or the innards of MacVim,
so I'm at a loss to go any further.
I've attached a log of all the configure and make output.
BTW, the MacVim repo is about 60 patches behind Vim.
