Comment (by saherr1969):

 Yesterday I ran:
 {{{
 port selfupdate && port installed outdated && port upgrade outdated &&
 port -q reclaim
 }}}
 Like others, it failed with:
 {{{
 --->  Computing dependencies for mpich-default
 Error: Dependency 'gfortran' not found.
 }}}
 I then followed mndavidoff's suggestion of installing {{{mpich-default}}}
 as a requested port.  This was successful.

 When I re-ran {{{port selfupdate && port upgrade outdated}}} it ran
 through the {{{octave}}} build until it ran into the destroot error.  This
 suggests that the maintainers of {{{mpich-default}}} need to modify their
 portfile somehow to allow this to be correctly processed as a dependency
 of {{{octave}}}.
 {{{
 --->  Staging octave into destroot
 Error: Failed to destroot octave: command execution failed
 }}}



 Like previously reported, the log file contains:

 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 {{{port upgrade outdated}}} command to upgrade octave.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  {{{port upgrade outdated}}} (SUCCESSFUL)!!!!!!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.
