Return code 127 means that Nagios wasn't able to start the plugin executable - as you already found out from your googling, it usually means that either the plugin is missing altogether, is in a different directory from where Nagios expects it, or that it is not executable for the nagios user. Note that it could also be permissions on one of the directories on the path to the plugin.
In most distributions I have seen, plugins are either in /usr/lib/nagios/plugins, or in /usr/lib64/nagios/plugins. Maybe Fruity somehow changed the directory from lib64 to lib or vice versa? You say that some checks are working and some aren't. Find one of the plugins that works, and one that doesn't, and compare the permissions and file locations. And finally, if you have turned on one of the hardening mechanisms (such as SELinux or AppArmor), a plugin may not be executable even with the right permissions. Since you say it happened when you used Fruity, my first guess is that it somehow changed the directory where Nagios looks for plugins.
