"Error detected while processing ../php.vim"

Here's a minor irritation with the vim port (editors/vim-lite, and probably the others). When I go to edit a php file I get this non-fatal error:"~/somefile.php" 99 lines, 2345 charactersError detected while processing /usr/local/share/vim/vim72/syntax/php.vim:line 479:E10: \ should be followed by /, ? or &line 482:E10: \ should be followed by /, ? or &line 488:E10: \ should be followed by /,
