installation error with MRTG package, help

["Wang Hui" <hwang@ustc.edu>]

Hi all,

When I want to pkg_add the mrtg package from the OpenBSD3.4 packages directory, I failed.  There seemed that there were errors with versions between the different needed dependent packages .  For example :

# pkg_add mrtg-2.9.12a.tgz
pkg_add(gd-1.8.3): add of dependency `png-1.0.8' failed!
pkg_add(gd-1.8.3): add of dependency `freetype-1.3' failed!

But in fact, there is a png-1.2.5p1.tgz package within the directory and I have already installed it . And so do freetype package. There is a freetype-1.3.1p1.tgz package .   I am puzzled what to do next.  Download all the source from ports, and compile them all?   Or any else?  I expect your suggestion. 

Thanks in advance. 

Best regards, 
Wang Hui
