Hi,
I have just tried without any problems:
[spataro@hal ~]$ svn co https://subversion.gsi.de/fairroot/fairsoft/trunk ttt
A ttt/tools
A ttt/tools/configure
A ttt/tools/rootconfig.sh
A ttt/tools/ApMon_cpp-2.2.6.tar.gz
A ttt/tools/ApMon_solaris.patch
A ttt/tools/ml-gsoapclient-2.7.10.tar.gz
A ttt/tools/ml_gcc4.3.1.patch
A ttt/tools/ml_gsoap_solaris_suncc.patch
A ttt/tools/rootconfig_grid.sh
Maybe it was just a momentary problem. Is it possible you are installing it in an already existing folder with an older package version?
