Out of tree build issue

I'm building on AIX 5.3 but I'm thinking this is on most (all?) platforms.

I'm doing an out of tree build and got an error with:

/usr/local/build/postgres-9.0.4/../../src/postgresql-9.0.4/src/backend/utils/cache/relcache.c:57:30: error:
catalog/schemapg.h:No such file or directory 

I think the symbolic link is wrong.  It is currently set to:

ls -l src/include/catalog/schemapg.h
lrwxrwxrwx   1 root     system           62 Jun 12 15:14 src/include/catalog/schemapg.h ->
/usr/local/build/postgres-9.0.4/src/backend/catalog/schemapg.h

and it probably should be pointing to:

/usr/local/src/postgresql-9.0.4/src/backend/catalog/schemapg.h
