Too many binary packages are missing

[Yuri]

I am updating i386 system (portupgrade -aP) and whole lot of binary 
packages are missing.
For example, gcc-4.5.0, qt4-corelib are examples of large packages that 
are missing that don't require too many dependencies and are very basic.

I know, it may be caused by failed dependencies, copyright restrictions, 
etc. But it's hard to imagive why they are missing for these two: no 
copyright restrictions, and almost no dependencies.

This unfortunately slows down many people.
Is there any solution to this problem? Maybe people just forget about 
this build server and some minor fix wil help?
