Martin,

Well, thanks for jumping in! We need all the help we can get ;)

I changed the execute bit as you suggested and recompiled, no luck, still the same error message.

Below is the output you wanted me to look at, its a bit beyond me so I include both a brief grep summary and then the whole enchilada. I do note that my output is different from yours, but I'm not sure how to interpret.

I also thought about removing curl from my system, but when starting to do so with Synaptic, it looked like if I removed libcurl I would trash an awful lot of my system. I did download and install the latest curl 7.18.1 on top of the other one, put /usr/local/ to the start of my PATH, reinstalled RCurl, and still the same erro message comes up.

So, what does it mean that the output of nm is different on our systems and is it important?

Thanks, Mark
