portmaster is not always recursive

[Miroslav Lachman]

Hi,

I have some problem with portmaster.
If I do upgrade of graphics/gd, portmaster check and upgrade all 
dependencies of gd (png, jpeg, pkg-config, freetype) but if upgrade of 
gd is called by upward recursive upgrade of jpeg library, I end up with 
new jpeg, new gd, new mrtg, but old png. It means that png was not 
upgraded as dependency of gd.

root at ararat ~/# pkg_info -rR jpeg-6b_7
Information for jpeg-6b_7:

Depends on:
Required by:
mrtg-2.16.2,1
gd-2.0.35,1


Upgrade of jpeg and all ports that depend on it

root at ararat ~/# portmaster -r jpeg-6b_7

===>>> The following actions were performed:
         Upgrade of jpeg-6b_7 to jpeg-7
         Upgrade of gd-2.0.35,1 to gd-2.0.35_1,1
         Upgrade of mrtg-2.16.2,1 to mrtg-2.16.2_1,1



root at ararat ~/# pkg_info -R jpeg-7
Information for jpeg-7:

Required by:
gd-2.0.35_1,1
mrtg-2.16.2_1,1


Upgrade of png must be done manualy:

root at ararat ~/# portmaster png-1.2.35
         Upgrade of png-1.2.35 to png-1.2.38


root at ararat ~/# pkg_info -r gd-2.0.35_1,1
Information for gd-2.0.35_1,1:

Depends on:
Dependency: png-1.2.38
Dependency: jpeg-7
Dependency: pkg-config-0.23_1
Dependency: freetype2-2.3.9_1


root at ararat ~/# pkg_tree gd
gd-2.0.35_1,1
|\__ png-1.2.38
|\__ jpeg-7
|\__ pkg-config-0.23_1
  \__ freetype2-2.3.9_1


Can we consider it as bug, or is it expected / feature?

This is on 7.2-RELEASE i386 GENERIC with portmaster-2.9 and fresh ports 
tree (`portsnap fetch update` this afternoon).
