Upgrading php with pkg

[Ivan Voras]

Hi,

It's time for my yearly rant about pkg seemingly not being able to upgrade
whole sets of dependencies while installing or upgrading packages.

In short, if we have this:

package A depends on package B, which depends on package C

...upgrading package B *must always* result in an upgrade to package A, and
*must* cause an upgrade of package C *iff* the new version of package B is
linked with a different version of package C (e.g. if it depends on a newer
version of package C).

Using heuristics such as checking versions encoded in .so filenames are
rarely enough because (upstream) developers are lazy. I can give examples
from the PHP-Apache-PostgreSQL stack at request.

If this is not done, we have the situation described here:

The post is somewhat strongly worded, and I believe it will be even more
strongly worded a year from now ;)
