Software Updates: "... requires plug-in ..."

[yaru22]

Hi,

I'm using Eclipse on Ubuntu Feisty. I recently tried to install PDT to
work with php. If I use Software Update to install this plugin, it
says "... requires plug-in org.eclipse.something." So I try to install
that 'something' by using Software Update, and it again says "...
requires plug-in org.eclipse.something else." So I try to install that
'something else' by using Software Update and it keeps giving me the
same messages. I couldn't install any of it yet because the dependency
keeps going on and on and on.

Is there a way to install a plug-in without worrying about dependency
issue? Do I have to track down everything and install them one by one?

Thank you.
