Building and installing from source may keep old stuff in the
previous installation path.
If you don't want that such kind of problems occur you should
consider to uninstall QGis (make uninstall) before compiling it again.
I ran ldd /opt/qgis-1.8.0/bin/qgis | grep "libqgis" and got this:
libqgis_core.so.1.8.0 => /home/StroeblB/apps/lib/libqgis_core.so.1.8.0
(0x00007fa8e9291000)
libqgis_gui.so.1.8.0 => /home/StroeblB/apps/lib/libqgis_gui.so.1.8.0
(0x00007fa8e8d90000)
libqgis_analysis.so.1.8.0 =>
/home/StroeblB/apps/lib/libqgis_analysis.so.1.8.0 (0x00007fa8e8aef000)
so obvoiusly it is not sufficient to only change the CMAKE_INSTALL_PREFIX?!
Shared lib are loaded by the OS, so old stuffs could blind new ones.
Anyway you could use the LD_LIBRARY_PATH enviroment variable
to override the path where to search libraries.

Hi Giuseppe,
thank you for your help. It turned out my build was linking to some older
installation (at least as far as I understand).
As I am not familiar with compiling software, may I ask you to help me
understanding what was going on? I basically followed
http://hub.qgis.org/projects/quantum-gis/repository/revisions/master/entry/INSTALL
to install into $HOME/apps
only recently did I change the CMAKE_INSTALL_PREFIX to /opt/qgis-1.8.0
when I saw the tip at
http://hub.qgis.org/wiki/quantum-gis/Building_QGIS_from_Source
I ran ldd /opt/qgis-1.8.0/bin/qgis | grep "libqgis" and got this:
libqgis_core.so.1.8.0 => /home/StroeblB/apps/lib/libqgis_core.so.1.8.0
(0x00007fa8e9291000)
libqgis_gui.so.1.8.0 => /home/StroeblB/apps/lib/libqgis_gui.so.1.8.0
(0x00007fa8e8d90000)
libqgis_analysis.so.1.8.0 =>
/home/StroeblB/apps/lib/libqgis_analysis.so.1.8.0 (0x00007fa8e8aef000)
so obvoiusly it is not sufficient to only change the CMAKE_INSTALL_PREFIX?!

I compiled current master and got an error when starting QGIS:
Traceback (most recent call last):
File "", line 1, in
ImportError: /opt/qgis-1.8.0/share/qgis/python/qgis/core.so: undefined
symbol: _ZNK11QgsMapLayer3crsEv
remove the directory /opt/qgis-1.8.0/share/qgis/python/qgis/, it contains
old stuff (have a look at its modification date before).
