It works fine here.

Can you attach the main.log?

Perhaps there is some undeclared dependency. Use "sudo port selfupdate" and then "port outdated" to see what else is outdated, and update some other ports first, then come back to pango later.

If that doesn't help, run this script to check for ports referencing libpng12.

Hi folks,

thanks for your hints. The problem was "cairo"

Replying to alexander.zimmermann@…:

How inexplicably strange. pango of course declares a dependency on cairo, so MacPorts should have upgraded cairo first before trying to upgrade pango. I do not know why it did not.

[alexander.zimmermann@…]

But did cairo get a rev bump for the new libpng? I'm not a macports expert, but how can macports know that it should rebuild cairo?

[alexander.zimmermann@…]

BTW, I have the same problems with pstoedit and ghostscript... (see Ticket #28048)

Yes, in r75159.

Because it received a revbump.

Regarding the description of duplicate ticket #30522:

Port upgrade does upgrade dependencies in the correct order (provided they are correctly declared in the ports). If you have a reproducible test case where it does not do that, please provide it. That would be a bug.

Detecting when a new revision of a port needs to be built because a dependency has a newer library version is a related but separate problem, and is being worked on by one of our GSoC students.
