I just installed MapServer 6.4.1 in Linux Mint and got this error (Opera dragonify) after passing an url in my localhost:

I use gdal-1.11.2 (installed from source) and MapServer was installed with apt-get (UbuntuGis stable). In my Synaptic Package Manager I found 'libgdal1h', not sure if this would be related. Apache version here:
