With Snapshot 74 on OS X ≤ 10.9, no editing window appears

[GoogleCodeExporter]

MacVim Snapshot 74, OS X 10.9.5.  Launch MacVim — no window appears.  Invoke 
⌘N New Window — no window appears.  Note that ⌘, Preferences still works, 
though.

If I run /Applications/MacVim.app/Contents/MacOS/MacVim at the shell, I see the 
error message (and it hangs until I press Ctrl-C):

dyld: Library not loaded: 
/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/libperl.dylib
  Referenced from: /Applications/MacVim.app/Contents/MacOS/Vim
  Reason: Incompatible library version: Vim requires version 5.18.0 or later, but libperl.dylib provides version 5.16.0
^C

Taking the hint, if I transplant /System/Library/Perl/5.18 from an OS X 10.10 
machine onto 10.9, then it works.

I consider this to be a bug since 1) Info.plist does not require a Minimum 
System Version.  2) Nor did MacVim come bundled with Perl 5.18 3) MacVim did 
not degrade gracefully with the lack of the exact version of Perl.
