Setting libpng, libjpeg libdir for Ubuntu 11.04

Thanks a lot for the update. Make and install went fine. I however had a error after running root as following:

Couldn’t find font “-adobe-helvetica-medium-r---10-----*-iso8859-1”,
trying “fixed”. Please fix your system so helvetica can be found,
this font typically is in the rpm (or pkg equivalent) package
XFree86-[75,100]dpi-fonts or fonts-xorg-[75,100]dpi.

I follow the post [url]]Adobe helvetica on ubuntu 11.04 installing the extra packages, reboot, and make root again but the error still persist. Here is outcome of ps -aef | grep xfs

114 1050 1 0 May07 ? 00:00:00 /usr/bin/xfs -daemon -user debian-xfs -droppriv
root 1065 1 0 May07 ? 00:00:00 /usr/bin/xfstt --daemon --notcp
davoudi 4916 1954 0 15:30 pts/0 00:00:00 grep --color=auto xfs

so it seems that sever for fonts is running. Any help or advise.
