Details:

By testing more and more packages, it turned out that the fl-core package has
similar integer problems as the parallel package. By installing fl-core via 

pkg install -verbose -forge fl-core
 
the following error occurs with gcc 4.8.5 on Ubuntu 12.04: 
+verbatim

fl_compose.cc:757:39: error: ‘sysconf’ was not declared in this scope
   return sysconf( _SC_NPROCESSORS_ONLN);
 

Beside the wrong integer size, the unistd.h header is not included to declare
sysconf and _SC_NPROCESSORS_ONLN. 

The attached patch will fix both problems.
