I want to install PHP 5.3 on Ubuntu Intrepid. To install apxs, I need to install libaprutil1-dev, which depends on libdb4.6-dev. When I look at installing that, apt-get wants to remove the currently installed libdb-dev and libdb4.7-dev. Any advice on how to proceed?

[root@server:/usr/local]
#> apt-get -s install libaprutil1-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

  libaprutil1-dev: Depends: libdb4.6-dev but it is not going to be installed
