Thank you for this analysis.
I have following options for ImageMagick-nox11

Options        :
         16BIT_PIXEL    : on
         BZIP2          : on
         DJVU           : off
         DOCS           : off
         FFTW           : off
         FONTCONFIG     : on
         FPX            : off
         FREETYPE       : on
         GRAPHVIZ       : off
         GSLIB          : off
         HDRI           : off
         JBIG           : on
         JPEG           : on
         JPEG2000       : on
         LCMS2          : off
         LQR            : off
         LZMA           : off
         MODULES        : on
         OPENEXR        : off
         OPENMP         : off
         PDF            : off
         PERL           : off
         PNG            : on
         TESTS          : off
         THREADS        : on
         TIFF           : on
         WEBP           : off
         WMF            : off


So it doesn't need dependency on glib and pcre (and python brought by glib)
Can ports Makefile be modified to use glib conditionaly only if options 
requiring it are selected?

I am not sure about gettext. I have NLS disabled in make.conf on our 
poudriere builder for all ports and it was not used before version 6.9.5.5
