Comment (by dmkallan):

 Replying to [comment:2 ryandesign]:
 > Until the ports are fixed, you can avoid the problem by downgrading to
 Xcode 11 and the Xcode 11 version of the command line tools.


 As an alternative to downgrading, you can always edit the db53 Portfile
 and use configure.cflags-append to tell gcc not to error out on implicit
 functions (no-error=implicit-function-declaration):

 1) Open the Portfile in a text editor, such as, for example:

 {{{sudo vi `port dir db53`/Portfile}}}

 2) Add the following line at the top level (maybe after configure.args):

 {{{configure.cflags-append  -Wno-error=implicit-function-declaration}}}

 Not really a fix, but for many packages that fail config on Xcode 12 and
 Silicon, this may at least get you around the issue until the port is
 updated.
