Current CVS - something broken in contrib

In any contrib module 'make installcheck' runs infinite time...

For example, contrib/ltree
% gmake installcheck
gmake -C ../../src/test/regress pg_regress
gmake[1]: Вход в каталог `/spool/home/teodor/pgsql/src/test/regress'
gmake[1]: `pg_regress' не требует обновления.
gmake[1]: Выход из каталог `/spool/home/teodor/pgsql/src/test/regress'
../../src/test/regress/pg_regress ltree

postmaster doesn't take a CPU time...
