actually, even more importantly the reason to drop this is because it is wrong
on linux. When building gdal it will link to a specific version of libproj (ex
libproj.so.3), with the current implementation, at runtime it will try to load
libproj.so. This does not existing in non -dev packages

I'm +1 on this. I too found it confusing that Proj.4 worked in this way and no

Ivan,
I don't
Even,
I'm +0 on this change.
On the one hand, I *like* the fact that the dlopen() approach means
that adding libproj.so after the fact means that GDAL starts
supporting coordinate system conversion without a rebuild. On the
other hand, it isn't clear why we do this only for libproj.
I have
ht?

Red Hat / Centos / Scientific Linux 6 use proj4 v4.8.x

Well that would be documented in the release

I think you are
+1
I’ve been tricked by this several times where I think I have gdal successfully
compiled and then go to reproject something only to find out it can’t :-(

Hi,
Currently the default mode of linking GDAL with proj.4 is to use dynamic
loading mechanism
(dlopen on Unix, LoadLibary on Windows). I believe the reason for that was that
it could have
make it easier to use an alternate projection engine, but apparently nobody
cared enough to
plug a new
