Comment:

 Duplicate #57971 says using `-std=c99` worked, but that surprises me. As
 Ken pointed out above, the port blacklists compilers that don't understand
 `-std=c++0x`. No compiler on Tiger understands c++0x, which leads to the
 message `All compilers are either blacklisted or unavailable; defaulting
 to first fallback option`. So either the software no longer requires c++0x
 and we should remove that blacklisting and add `-std=c99` and inform the
 developers of that, or the software still does require c++0x in which case
 we should remove the custom blacklisting and use the cxx11 1.1 portgroup.
 I will investigate.
