New dependencies of ImageMagick-nox11 - are they necessary?

[Miroslav Lachman]

I upgraded ImageMagick-nox11: 6.9.4.3,1 -> 6.9.5.5_1,1 and found these 
new dependencies:


New packages to be INSTALLED:
         gettext-runtime: 0.19.8.1
         glib: 2.46.2_2
         python27: 2.7.12
         pcre: 8.39

I did this in one small jail where I don't want any unnecessary 
packages. This was minor update of ImageMagick so I am surprised with 
these not so small new dependencies.

Are they really necessary even for nox11 variant of ImageMagick?
