Comment (by chrstphrchvz):

 Do not rely on [https://packages.macports.org] for determining whether a
 port can build; that site is only for prebuilt packages of ports which
 allow binary redistribution. Even if sphinx4 can build, MacPorts likely
 will not offer a prebuilt package for it since there is currently no
 license specified in its Portfile, and so no way for MacPorts to be
 certain binary redistribution is allowed.

 If you want to check whether a port is known to build, please use
 [https://ports.macports.org]; in the case of sphinx4 this is mostly
 unknown because almost no builds of the port have been requested since the
 launch of [https://ports.macports.org] a few years ago.
