I'm having major issues trying to install this external.
I have added the path to the extern in PD>paths.
The error dump coming up is:

/Users/chris/Desktop/earplug~osx/earplug~.pd_darwin: dlopen(/Users/chris/Desktop/earplug~osx/earplug~.pd_darwin, 10): no suitable image found.  Did find:
    /Users/chris/Desktop/earplug~osx/earplug~.pd_darwin: mach-o, but wrong architecture
earplug~: can't load library

On Mac OS X.
I downloaded this extern from here from the link that says osx. I assume I don't have to compile it or anything?

I got this working in the end.
I can't remember how

i guess that you had the filename included in the path. path should have just been:

/Users/chris/Desktop/earplug~osx

I remember trying that! it was something more wierd.

has anyone had the error:
error reading impulse reponse file 'earplug_data.txt'!
when first using [earplug~]?
