Well said. What I was trying to get at is
for packages with "too many" dependencies, identify options that
dramatically reduce the dependency footprint without making the
package significantly less useful in the normal case. Move those out
of PKG_SUGGESTED_OPTIONS.
For graphviz:
These options are enabled by default:
gd gtk lua pangocairo perl rsvg swig tcl x11
These options are currently enabled:
gd gtk lua pangocairo perl rsvg swig x11
[I have -tcl in PKG_DEFAULT_OPTIONS.]
I'd drop lua, perl, swig from that. I have yet to meet anyone who uses
them.
I'd drop rsvg as long as that lib pulls in libgsf.
I don't know about pangocairo.
Objections? Jens - what do you think?
