Sounds like you didn't do the rebuild correctly.  The full recipe is

1. Change BLCKSZ in include/config.h (after running configure).
2. Do a *full* compilation.  If you compiled already, do "make clean"  before "make all".  Do not rely on make
dependencies,because there  aren't any.
 
3. Install.
4. initdb.

No.  Page size is a pretty fundamental thing...
