ports index broken, expat2 is too new for current apache2 on 5.4-STABLE

[Brian Ross]

Ok, I got myself into a spot here:

As I was trying to install Apache 2.2 from ports, I ran into its  
expat2 dependency, but it's at a version beyond the version my  
current version of apache is using. So I decided to just overwrite  
the old expat2 install not thinking (yes, I know, not good...) that  
it would affect much. It really hasn't but now I have apache 2.0.54  
complaining that I no longer have shared object support since apache  
was compiled with the older version of expat2 (1.95_8 or something  
like that).

In the process of all this, my ports index got corrupted and now I  
can't "make index" in /usr/ports. I also now have an expat install  
that is further along than the portsdb thinks it is. I get the  
following when I try to "make index" in /usr/ports:

unless it is explicitly permitted in step 6!

==========

What's the best way for me to recover from this situation? My first  
try was to use portdowngrade to install an older expat2, but without  
INDEX-5, it can't find it (at least I think that's why). CVS to get  
the older expat2? (Any pointers, please help...) Anybody successfully  
running apache22 and apache2 alongside each other on 5.4-STABLE?

Any guidance is greatly appreciated!


Thanks,
