 Hi Ryan!  Thanks for taking care of this.

 > Thanks. I assume you are the maintainer of this port? Your email address
 in this Trac ticket does not match the one listed in the portfile.

 I'm the maintainer of Vcsn.  Yes, I'm akim at lrde.epita.fr.

 > You added a library dependency on lib:libltdl:libport but we have no
 port called "libport". libltdl is part of the libtool port; is that what
 you meant? If so, it should be written "port:libtool". "lib:"-style
 dependencies are only used when it is desired to allow non-MacPorts
 software to satisfy the dependency, and usually we do not desire that.

 OK.  I don't know where I took this line from.  Note that there is

 {{{
 depends_run         path:lib/libltdl.a:libtool
 }}}

 provided as an example there:
 https://guide.macports.org/chunked/reference.dependencies.html

 > You added a runtime dependency on port:ccache. Usually ccache is used at
 build time, at the discretion of the user and their macports.conf
 settings. Is ccache really needed at runtime? If so, the dependency should
 be written "path:bin/ccache:ccache" to allow the ccache-devel port to
 satisfy the dependency.

 OK, I fixed that.  Yes, vcsn runs compilation at runtime, and uses ccache
 to ensure that modules that were previously compiled will no longer be
 recompiled.

 > Some of the compilers you've blacklisted don't exist anymore, for
 example "*clang-2.*". The oldest clang we have in MacPorts today is
 clang-3.3.
 >
 > Since this project requires C++11, it should probably start by using the
 cxx11 1.0 portgroup, which sets some blacklisting and other necessary
 options. The blacklist can then be augmented if the project has compiler
 restrictions above and beyond the need for C++11.

 Good to know, thanks!

 I have attached two Portfiles: one for vcsn, another for obsoleting
 Vaucanson.  I have also added a new diff from the previous vaucanson
 Portfile to the new vcsn Port file.  Thanks again!
