[lqfb-main] error while installing core

[Jan Behrens]

Hi Piet,

the LiquidFeedback core needs PostgreSQL installed on your machine. It 
appears like on your machine the necessary declarations for the libpq 
client library of PostgreSQL could not be found.

Can you provide the following information:

- Version of the LiquidFeedback Core you want to install
- Version of PostgreSQL installed on the machine
- Output of the commands
     pg_config --includedir
   and
     pg_config --libdir


Regards
Jan Behrens
