How to decide between them is to configure the last version of GRASS GIS which worked for you. If you can configure and compile from scratch that old version but not the new one, you can try a version in between these two, the go to beginning of this sentence (aka bisect). This way you find the change in GRASS GIS. In case both the old and the new version don't configure, the change is in your system.<br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space"><br>

<div>I would say the problem is not zlib, but missing C++ compiler (at least on my machine, /lib/cpp eventually points to /usr/bin/cpp-5), although I don't know why ./configure would catch that problem earlier since a successful report contains:</div>
