Adding "cairo" and "pango" flags to USE solved this build issue for me.
And prior, the cairo package needed to be built with "svg" added to USE.

I ran into this as well.
The RDEPEND structure does not match how the configure flags are passed.
If you have USE="-X gnome gtk cairo"
then it tries to build the gnome, gtk and cairo stuff, but because of -X, it
does not RDEPEND on them.

If we look at the config.log, we get this:
configure:30817: result: yes
configure:30913: checking for PANGOCAIRO
configure:30921: $PKG_CONFIG --exists --print-errors "pangocairo >= 1.14.10"
Package pangocairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `pangocairo.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pangocairo' found
configure:30924: $? = 1
configure:30939: $PKG_CONFIG --exists --print-errors "pangocairo >= 1.14.10"
Package pangocairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `pangocairo.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pangocairo' found
configure:30942: $? = 1
No package 'pangocairo' found
configure:30970: result: no
configure:30972: WARNING: pangocairo library not available

And similarly for gdk-pixbuf.

Ok, I tested a few build combinations, and I'm going to adjust the RDEPEND
structure to match.

Doing this fails:
emerge --unmerge cairo pango ; USE="-X -cairo -pango" emerge graphviz
Because it seems the dot tool really needs the pango library now when you are
using an external libgd. Look at cmd/dot/Makefile.am - WITH_MYLIBGD is false
because we use the system libgd.

USE=X -> libXaw, builds the lefty tool

I've added an -r1 of the ebuild that changes this. It does mean that
cairo+pango are no longer optional. If you object to that, patch/get upstream
to allow disabling pango. The Makefile.am for dot can use some heavy
refactoring anyway.

I don't think the solution is entirely satisfactory.  Pulling in cairo is fine
- but pulling in pango also pulls in a big heap of X related packages, and
removing graphviz is a requirement for a couple of packages which I need.  On a
server such as mine with no X support, this is a step backwards:

tornado log # emerge -uDNa graphviz

These are the packages that would be merged, in order:

Would you like to merge these packages? [Yes/No] no


(All these dependencies are pulled in because of the pango dependency
requirement - which has no option to disable).  I guess you could argue that
the real fix is to fix pango but still...

What about the fix at
http://www.mail-archive.com/openpkg-users@openpkg.org/msg03524.html   ?

That patch is a good start, but it just makes the cmd/dot/Makefile.am mess
worse.
If somebody wants to post a version that factors out the massive duplication
there (eg move the common stuff to some new variables), and also send it to
upstream, I'll gladly accept it.

media-gfx/graphviz-2.16.1-r2 is in the tree now, with pango/cairo optional
again.
"use X || use cairo || use gtk" will all trigger the cairo output module (and
thus the pango text layout mode).

Many thanks for the fix!  All builds fine now (in my case, without
cairo/pango).
