The attachment is a screen shot of error messages whenever I start Wireshark. I've re-installed the program three times using the provided directions to the best of my abilities and the errors keep appearing. During the installation process I've installed GTK+ and moved ChmodBPF to the root StartupItems folder in addition to dragging the Wireshark application from the package to the Applications folder. I need to install this program for a networking class and I'll admit that I'm not a super-techie person although I can find my way around a computer and I do have programming experience on a PC. Any assistance you can provide would be greatly appreciated.
I'm not entirely sure what the root cause of the problem is, but there 
is discussion about it (which includes a solution) in bug 3163:
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3163

Anyway the error just means that Wireshark can't load the SNMP MIBs. If you're not decoding SNMP then you can just ignore the errors.
(I'm not sure that bug really should be closed; maybe Wireshark's 
default path for SNMP MIBs is not correct.)
