Under Windows: Libvips is not installed. Imagemagick is not installed

[hjuefricke]

On windows the routine to check Vips does not work. The system command "which" does not exist on win-os
Changing the routine in image_backen.rb made it work for me:

def command?(command)
host_os = RbConfig::CONFIG['host_os']
if host_os =~ /mswin|msys|mingw|cygwin|bccwin|wince|emc/
system("where #{command} > NUL 2>&1")
else
system("which #{command} > /dev/null 2>&1")
end
end

Thanks for your great work!!

Ahh, I'm sorry about that! Didn't occur to me to check. You can roll back to 2.0.4 until I can cut a new release to fix it properly

Thanks for the quick reply! I fixed it and it works for me until the next release.
