New description:

 For context... I'm using macports in a non-standard location and with no-
 root access. This port used to build but either due to compiler updates or
 port changes its now broken.

 Install fails in many ways with no attempt to force the compiler it gives
 errors related to Redefining typedefs (matching the comment next to the
 compiler blacklist). Forcing clang-mp-17 the build fails in a different
 place...

 {{{
 ...
 error: incompatible function pointer types passing 'void (void *,
 xmlErrorPtr)' (aka 'void (void *, struct _xmlError *)') to parameter of
 type 'xmlStructuredErrorFunc' (aka 'void (*)(void *, const struct
 _xmlError *)') [-Wincompatible-function-pointer-types]
 }}}
