I've installed postgres but when I try to install it's header files I get the following error:
he following packages have unmet dependencies:
libpq-dev: Depends: libpq5 (= 8.4.8-0ubuntu0.10.04) but 8.4.12-0ubuntu10.04 is to be installed
E: Broken packages
Thats when I run apt-get install libpq-dev. I've already done apt-get install postgresql and libpq5 would not update. (says it's already at newest edition)
