 A web search showed that QSqlDatabase is Qt's SQL Database class. Using
 {{{port search}}} for QSqlDatabase and QSQLITE provided no insight. So I
 then ran {{{port search --line Qt | grep -i sqlite}}} which revealed qt4
 and qt5 plugins. Because the MacPorts Portfiles web page lists qt5-sqlite-
 plugin, I installed that, successfully, and then retried the {{{port
 upgrade outdated}}} command to upgrade {{{octave}}}. Again it failed
 during the destroot processing.

 I reviewed the log file a bit higher and found:
 {{{
 :debug:clean Searching for dependency: qt4-mac
 :debug:clean Found Dependency: receipt exists for qt4-mac
 :debug:clean Searching for dependency: qscintilla-qt4
 :debug:clean Found Dependency: receipt exists for qscintilla-qt4
 }}}
 The qt4 items suggested I needed qt4 and not qt5 sqlite plugin. Proceeded
 to:

 1.  {{{port uninstall qt5-sqlite-plugin}}} (successful)
 2.  {{{port install qt4-mac-sqlite3-plugin}}} (successful)
 3.  {{{port upgrade outdated}}} (SUCCESSFUL)!!!!!!
 Looking at the "source" for the portfile and found:
 {{{
 variant qt4 conflicts qt5 description {build the GUI using Qt4} {
     PortGroup qt4 1.0
     depends_lib-append port:qscintilla-qt4
     configure.args-replace --without-qt --with-qt=4
 }

 variant qt5 conflicts qt4 description {build the GUI using Qt5} {
     PortGroup qt5 1.0
     qt5.depends_component qttools sqlite-plugin
     depends_lib-append port:qscintilla-qt5
 ...
 }}}
 This suggests the fix for the destroot issue is to add a dependency check
 for {{{qt4-mac-sqlite3-plugin}}}.

 I have no clue how to do this so hopefully the maintainers of {{{octave}}}
 can add this.
