check_ldap, check_radius or check_pgsql don't compile even though configure output says the required libraries are present

Due to a bug in the 1.4.7 and 1.4.8 releases, check_ldap, check_radius and check_pgsql won''t compile if MySQL libs are present even if configure output says the required libraries are present. This is fixed in 1.4.9

Here's the easiest way to compile and install these plugins:

• cd to the plugins/ directory of the Nagios-plugins source tree
• For each missing plugin, run "make check_", eg //$ make check_ldap//
• Copy all pugins built above to your Nagios plugins directory (usually /usr/local/nagios/libexec/).
