Unmentioned dependency on pkg-config

[immesys]

If pkg-config is not present, then this line in c6/hashtable/configure.ac gives a syntax error during configure:

checking for ranlib... ranlib
./configure: line 3830: syntax error near unexpected token `CHECK,'
./configure: line 3830: `PKG_CHECK_MODULES(CHECK, check >= 0.9.4)'
configure: error: ./configure failed for c6/hashtable/

Commenting out the line also works :-)

To be honest, the whole idea of using check ended up being kind of a pain -- I think adding the dependency is more trouble that it's really worth for the limited test fixtures it gives you...
