pgAgent build error,(Ubuntu)

Problem with building on Ubuntu:

Linking CXX executable pgagent
/usr/bin/ld: /usr/lib/gcc/i686-linux-gnu/4.8/../../../../lib/libpq.a(fe-auth.o): undefined reference to symbol 'error_message'
//lib/i386-linux-gnu/libcom_err.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [pgagent] Error 1
make[1]: *** [CMakeFiles/pgagent.dir/all] Error 2
make: *** [all] Error 2

pgAgent source 3.4.0
Ubuntu 14.02.2 x86
cmake version 2.8.12.2
wxWidgets 2.8.12
gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2
postgresql 9.3.6

Any advice?

С уважением,
Beholder .
