Looking at installed lib/pkgconfig/gazebo.pc, there is a pthread by itself:

Libs: -Wl,-rpath,${prefix}/lib/gazebo-4.0/plugins -L${libdir} -L${prefix}/lib/gazebo-4.0/plugins -lgazebo_transport -lgazebo_physics -lgazebo_sensors -lgazebo_rendering -lgazebo_gui -lgazebo_msgs -lgazebo_math -lgazebo_common -lgazebo -L/usr/lib -lboost_thread-mt pthread -lboost_signals-mt -lboost_system-mt -lboost_filesystem-mt -lboost_program_options-mt -lboost_regex-mt -lboost_iostreams-mt -lboost_date_time-mt 
CFlags: -I${includedir}/gazebo-4.0 -I/usr/include

removing pthread appears to fix compilation.

• changed state from "new" to "resolved"

pull request #1207 implements a way of keeping pthread in pkgconfig but using the corresponding -l

This has been failing on the jenkins precise machine for a while:
