Compiling v1.13 dev - configure: error: No usable boost::iostreams found

As you can see from the above line of your config.log, the linker cannot
find the library. This means it is not installed in a standard
location. You should pass the directory where it can be found to the
configure script via the LD_LIBRARY_PATH environment variable.

Best,

Ps. A new stable version of graph-tool (2.13) has been released.

Problem fixed. Also, thank you for the new release. I am still having trouble
with the boost::coroutines in Ubuntu 14.04 though but we are discussing that
already so no need to duplicate the discussion here.

Best,

Philipp
