Simply edit srcunx/gvxreg.c using the following sed script with your browser's executable file name substituting for [browser]: sed -i s/netscape/[browser]/ srcunx/gvxreg.c Install GSview by running the following commands: sed 's|GSVIEW_ROOT=/usr/local|GSVIEW_ROOT=/usr|' \ srcunx/unx.mak > Makefile && make && make install
