Can't install MySQL on Mountain Lion

I have clean 10.8 OS X (with Retina MacBook Pro).

I have totally the same situation like here Can't re-install MySQL on OS X Leopard after uninstalling

and similar with that https://stackoverflow.com/questions/5067787/re-install-mysql-in-mac-os-x-10-6-6

But in last case I have user mysql already.

When I'm trying to install it from package, i see in syslog next message

Seems to me problem in that place

Aug 22 08:08:57 nnn-laptop.local installd[330]: *** NSTask: Task create for path '/Volumes/mysql-5.5.27-osx10.6-x86_64/mysql-5.5.27-osx10.6-x86_64.pkg/Contents/Resources/preflight' failed: 22, "Invalid argument".  Terminating temporary process.

But content of preflight is:

#!/bin/sh
# 
# preflight - this script will be executed before the MySQL PKG
# installation will be performed.
#   
# If this package has been compiled with a prefix ending with "mysql" (e.g.
# /usr/local/mysql or /opt/mysql), it will rename any previously existing
# directory with this name before installing the new package (which includes
# a symlink named "mysql", pointing to the newly installed directory, which
# is named mysql-<version>)
#

PREFIX="/usr/local/mysql"
BASENAME=`basename $PREFIX`

if [ -d $PREFIX -a ! -L $PREFIX -a $BASENAME = "mysql" ] ; then
        mv $PREFIX $PREFIX.bak
fi

The last line is 18, there is no any 22nd line.

It appears this error is related the Apple's quarantine of downloaded applications. Usually it presents a dialog, but when it can't, it prevents the app from launching.

The indicative line is:

Aug 22 08:08:57 nnn-laptop kernel[0]: exec of /Volumes/mysql-5.5.27-osx10.6-x86_64/mysql-5.5.27-osx10.6-x86_64.pkg/Contents/Resources/preflight denied since it was quarantined by Safari and created without user consent, qtn-flags was 0x00000006

You could try copying the package out of the disk image, and then running xattr -dr mysql-5.5.27-osx10.6-x86_64.pkg on the package. See this post for more details.
