 The log says:

 As stated in [https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=281886
 another bug report]:

 > As noted in the [https://libcxx.llvm.org/ReleaseNotes/19.html
 #deprecations-and-removals libc++ 19 release notes], `std::char_traits<>`
 is now
 > only provided for `char`, `char8_t`, `char16_t`, `char32_t` and
 `wchar_t`, and any
 > instantiation for other types will fail.

 Here is [https://gitlab.freedesktop.org/poppler/poppler/-/issues/1462 the
 upstream bug report] about this. It was
 [https://gitlab.freedesktop.org/poppler/poppler/-/commit/b4ac7d9af7cb5edfcfcbda035ed8b8c218ba8564
 fixed in poppler 24.05.0]. The port needs to be updated. According to
 [https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1526 the
 upstream merge request], this change is binary incompatible, and some
 dependents like inkscape will need to be revbumped.
