<p>Hi Even,</p>
<p>Yes - indeed that seems to be the case. There seem to be two versions of libproj on the system:</p>
<p><span>/usr/local/lib/libproj.so.19 </span><span>and </span><span>/usr/lib/x86_64-linux-gnu/libproj.so.15<br /></span></p>
<p><span>The first was compiled by myself, the second seems have to be slipped in by the package manager.</span></p>
<p><span>And indeed spatialite seems to be the culprit - the only one that links to the old version.</span></p>
<p><span>Thanks a lot for your help!</span></p>
<p><span>Andreas</span></p>
