Odd - _vsnprintf has been used throughout the code for quite some time. I'm not sure why you'd just have an issue with it now. Make sure you have all of these libraries installed (32bit): libgcrypt, libgpg-error, libjpeg, libpng12, libstdc++, libpthread, libgcc_s, libXxf86vm, libXau, libXdmcp, libXext, libXdamage, libXfixes, libdrm, libX11, libGL, libxcb, libz, libdl, librt, libm, libc.
