Which VCS do you use?

Does MacVim make use of perl?  Do you have VCS 
wrapper scripts that use perl?

I have the same problem, when trying to use vcscommand script within a SVN 
working 
dir.

Vcscommand version 1.99.31 are installed into $VIMRUNTIME dir.

I do not use any wrapper scripts. 
My Mac has OS 10.6.1 with default installation of SVN and Perl installed.

Interesting point: After killing the hanging Perl process, the output of VCSLog 
command looked good in Vim.

I have the exact issue mentioned by Marco.Sorich

I saw similar behavior, with svk being the culprit.
Running ps -ef | grep svk showed perl executing /usr/bin/svk

Running svk by itself produces the following:
Repository /Users/lickea/.svk/local does not exist, create? (y/n)

Without the local repository, svk waits for input, halting the GUI.

Calling svk with a closed stdin means the program won't hang:
~ $ svk info . <&-
Repository /Users/lickea/.svk/local does not exist, create? (y/n)Unable to read
terminal settings in GetControlChars at
/System/Library/Perl/Extras/5.10.0/SVK/Util.pm line 199.

I don't have the correct environment to duplicate this issue, but it sounds as 
though
the "svn info ." command that is executed as part of the VCS type identification
routine is hanging.

I recommend disabling the SVK part of the vcscommand plugin until the SVK issue 
is
resolved by putting some variant of the following in your vimrc:

let VCSCommandSVKExec='disabled no such executable'

Is there a way to identify the affected version of the Mac OS from within VIM?

Thanks! Disabling the SVK is enough to fix my problem.

And As far as I know， SVK development is discontinued.

Thanks for the info re: SVK.  However, I'm not really sure what to do here.  I 
can
probably just disable the SVK extension by default (at least, on the Mac), but 
I'm
wary of doing that when, in fact, the user has installed SVK so presumably 
intends to
use it.  I wonder if there's a better way to identify whether a directory is 
under
SVK control that doesn't hang the system.

SVK is installed by default on a Mac..

How about changing the line to:

let statusText = system(VCSCommandGetOption('VCSCommandSVKExec', 'svk') . ' 
info "' .
directoryName . '"',"no")

If the user has svk setup, there is no prompt.
If the user does not, the prompt is answered without creating a local repo.

Patch: If svk thinks it's being run interactively, this will respond negatively 
to the prompt:
Repository $HOME/.svk/local does not exist, create? (y/n)

This should prevent hangs with MacVim.

I can confirm that lickea's patch works.  I tried both git repos and svk repos 
in
both macvim and regular command-line vim on snow leopard.

Thanks for the confirmation.  I'll release it shortly.
