apt-get broken dependencies

[Alex Dean]

I'm on Debian unstable, and I wanted to install the GD libraries for  
PHP.  (Post on thumbnailing got me thinking...)  I got a message that  
there are unmet dependencies.  I think I generally know what that  
means, but I have no idea what to do.  Do I have to just wait until  
this is fixed in the repositories?

What is t1lib1 (mentioned below)?  The package information for php4- 
gd don't mention it as a dependency... http://packages.debian.org/ 
unstable/web/php4-gd

thanks,
alex

ps - Here's the commands I ran...

kiltlifter:/etc/php4/apache2# apt-get update

<lots of update messages removed, no errors>

kiltlifter:/etc/php4/apache2# apt-get install php4-gd

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:

The following packages have unmet dependencies:
   php4-gd: Depends: t1lib1 but it is not installable
