You need to pass --enable-shared-pp to configure as well. I'm not  
sure what the difference between these two options is. I can easily  
move the versioning information to the configure portion for --enable- 
shared instead, but I'm not sure this is the correct behavior. Please  
let me know if this is preferable.
