postgresql-9.1-postgis and gdal-bin conflict

[strk]

the gdal-bin package requires postgresql-9.1-postgis-scripts which installs topology.control file as done by postgresql-9.1-postgis.

As a result installing those two packages fails. See ​https://travis-ci.org/CartoDB/CartoDB-SQL-API/builds/14597983

$ sudo apt-get install -q postgresql-9.1-postgis gdal-bin

Hi, it seems that you have another repository providing postgresql and postgis since there is no PostGIS 2.1.0 package for Precise on UbuntuGIS. You should check why postgis 2.1.0 is installed and either only use the repository providing it or UbuntuGIS.
