 In [bf528304dd/macports-ports]:

 {{{
 subport dvisvgm-devel {}

 if {${subport} eq ${name}} {

     …

 } else {

     # devel

     …

     use_autoconf yes
     autoconf.cmd ${worksrcpath}/autogen.sh

     # Setting autoconf.cmd to a non-default value after setting
 'use_autoconf yes'
     # removes the automatic dependencies, so re-add them.
     depends_build \
         port:autoconf \
         port:automake \
         port:libtool

 }

 depends_build \
     port:asciidoc \
     port:pkgconfig

 }}}

 The second (outer) `depends_build` wipes out the `depends_build` specified
 for `dvisvgm-devel`. This caused CI builds to fail:
