I am trying to install EGroupware Community Edition 1.08 and needs to install JPGraph. However when trying to install JPGraph there was error saying that their jpgraph-3.5.0b1.tar.gz file is not in gzip format. Tried older versions (jpgraph-3.0.7.tar.gz) and another version on Sourceforge (jpgraph-3.0.7.tar.bz2) and got same result.
