From the stdio for rtl_433[1], it looks to me like there's a general problem with the build environment being able to fetch upstream deps.

I'm not sure what you mean... If you are referring to this output:

then that is the completely normal output that MacPorts will display when it is unable to find a precompiled binary of the port on our server. If a build has been scheduled on the buildbot, this will almost certainly be the case. (We check whether there is a binary before scheduling a build; if there is, we don't schedule it.) Lacking a binary, MacPorts then tries to build from source.

rtl_443 failed to build from source, and it looks like the relevant errors are:

-- Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) 
-- Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) 
-- Found LibRTLSDR: /opt/local/lib/librtlsdr.dylib  
-- Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) 
-- Could NOT find LibUSB (missing: LIBUSB_INCLUDE_DIR) 
CMake Error at CMakeLists.txt:105 (message):
  RTL-SDR development files not found.

Perhaps the port is just missing a build dependency on port:pkgconfig and/or a library dependency on port:libusb.

You can try building the port in trace mode (the "-t" flag) to reproduce the issue locally, then add dependencies as needed to resolve the issue, and submit a PR with whatever fix you come up with.

There is in fact also a general problem with the buildbot, which is that the SQLite database it uses to keep track of pending build requests became corrupted a couple days ago and I just noticed. Until I figure out what to do about that, the buildbot won't be able to build anything.
