and ./configure gives me
checking pkg-config is at least version 0.9.0... yes
checking for LIBPQXX... configure: error: Package requirements (libpqxx >= 2.6.8) were not met:

No package 'libpqxx' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBPQXX_CFLAGS
and LIBPQXX_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
