I did this but when I try do create a function the following message is
displayed:

" ERROR:  could not load library
"/usr/local/pgsql2/PLANSandTESTS/libtimes.so":
/usr/local/pgsql2/PLANSandTESTS/libtimes.so: undefined symbol:
assert_enabled "

Any ideas? Is there any file I should include during compilation? I
couldn't find any HOW-TO or something.

You need to rebuild the whole backend, not just your function.
