PHP5 install--apache seg fault 11

I compiled and installed PHP 5.0.2 successfully with a
number of configure options on Red Hat ES3. Everything went
fine--info.php page reported successful install with all my
config options. 

Then, I decided to recompile and reinstall to add a few
additional configure options. After doing this, I started
getting segmentation faults in apache when accessing PHP
pages. 

In an attempt to get things "back to normal", I tried a
very simple configure, followed by make clean, etc as such:


$ ./configure --with-apxs2 
$ make clean 
$ make 
$ sudo make install 

Unfortunately, this still doesn't work...apache seg fault
(11). 

Am I missing something here in the recompile steps? Do I
need to clear something out from previous installs to make
this work properly?
