  These are required for MySQL support in Kexi.

  If you want MySQL support in Kexi, you need to install the MySQL development
  files, ensure that mysql-config is in your path,  and run this configure script
  again, and finally run make; make install.  
  If you don't need MySQL support, you can simply run make; make install now.

    These are required by the libpqxx C++ library, which is used by
    Kexi's PostgreSQL drivers.

    The PostgreSQL C-API usually ship with PostgreSQL, but if you've
    installed from a distros package then these files may be part of
    a package called postgresql-devel or libpq-devel"

    Could not find the libpqxx $pqxx_parts_missing files.
    These are required by Kexi's PostgreSQL drivers.

    Note: Kexi requires the SHARED libpqxx.so library files.
          If you build pqxx library on your own, don't forget to use the
          --enable-shared option when you run libpqxx's configure script.
          This is necessary to compile the SHARED .so library, and
          not the STATIC libpqxx.a.

    The PostgreSQL C++ API can be downloaded from pqxx.tk or
    http://gborg.postgresql.org/project/libpqxx/projdisplay.php
    Grab the latest version (>=2)

# SUMMARY messages
  cat <<EOS
  These warnings are not critical, but without installing the files
  listed above Kexi will be compiled without PostgreSQL support.

  If you want PostgreSQL support in Kexi, you need to install the files
  listed above, then run this configure script again, and finally run
  make; make install.  If you don't, simply run make; make install now.
