How do i satisfy package dependencies?

[Igor Lumpus]

Hello,

In an earlier thread i reported a problem with yum update but
got no reply so i rebooted after the failed yum update and
tried it again. This time the output from yum update executed
as root is:

Resolving dependencies
....Unable to satisfy dependencies
Package php-ldap needs php = 4.3.8-2.1, this is not available.
Package php-mbstring needs php = 4.3.8-2.1, this is not available.

How do I fix this?

What happened the first time was that yum update froze during its operation.
It stopped at the point:
  xpdf 100 % done 121/261
There was no initial conflicts when it started and /var/logs/yum.log
only has entries from my last successful yum update in november.

If there is more info needed to answer my question then please post
it.

Thx
