I don't think so. Looks like an issue with your GDAL and/or proj.4 install.
The proj.4 string for EPSG:3857 reported above is wrong. It should be (as reported by gdalsrsinfo "EPSG:3857"):

+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext  +no_defs
