Comment (by joel-coffman):

 I managed to build successfully after temporarily renaming the iconv
 versions in `/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/`:
 {{{
 sudo mv usr/include/iconv.h usr/include/iconv.h~
 sudo mv usr/lib/libiconv.tbd usr/lib/libiconv.tbd~
 }}}
 After which cleaning and installing the port was successful:
 {{{
 sudo port clean inkscape
 sudo port -t install inkscape
 }}}
 (followed by restoring the original name of the iconv version in
 `/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/`).

 Temporarily renaming iconv doesn't seem like it should be necessary, but
 reporting it here in case others have a similar issue.
