configure.ac: boost 1.53 required
Commit 65f4f8c7 raised the required version number of the boost library to 1.53 (due to boost/graph/vf2_sub_graph_iso.hpp). configure.ac requires only 1.38 at the moment.
Please use the issue tracker only to report bugs (i.e. errors in the library that need to be fixed) or feature requests.
For questions about how to compile, install or use the library, please use instead the web forum at https://forum.skewed.de/c/graph-tool.
(If unsure, use the forum first.)
IMPORTANT: When opening new issues, please choose the BUG template from the drop-down menu, and fill out the required information.
