 Hi

 When calling the any plugin on Lion via telnet, it results in the same
 error (see below some modifications needed to successfully install)

 Trying 129.20.159.199...
 Connected to pr159199.med.univ-rennes1.fr.

 while it run fine using munin-run on the node computer

 sudo -u munin /opt/local/sbin/munin-run df

 and here is the corresponding munin-node.log

 ======================================

 I experience difficulties in installing minion node on snow leopard (PPC
 and intel core 2 duo as well as Lion / intel Xeon and i5)

 First of all, after installing, I tried to run
 sudo munin-node-configure --suggest --shell | sh

 I got an error

 Could not open plugin configuration directory: No such file or directory
 at /opt/local/lib/perl5/site_perl/5.12.3/Munin/Node/Service.pm line 81

 Looking at the code, I assumed that

 sudo mkdir /opt/local/etc/munin/plugin-conf.d

 could fix the issue… In fact the plugin folder could not be written by an
 admin and sh seems to be sudo, like

 sudo munin-node-configure --suggest --shell | sudo sh

 on Lion, none of the plugin succeeded in autoconf with message
 Non-zero exit during autoconf (1)
 So, I also had to run as munin user

 sudo -u munin munin-node-configure --suggest --shell | sudo sh

 (but there is still an  issue with asking for password if the precedent
 sudo is not recent enough…)

 it might be interesting to dig into that or at least to when it is
 suggested to run the munin-node-configure to add the proper command.

 thank you for your help
