For a software that I am installing in an ubuntu server, it needs the curl deb packages. When I try to install libcurl4-dev it says that this is a virtual package and I need to install libcurl4-gnutls-dev or libcurl4-nss-dev. What is the difference between installing one or the other?

PS: Is there any big difference between installing libcurl3 or libcurl4?

I would guess the biggest end-user difference between gnutls/nss is probably the license. As for the curl3 to curl4, this may be your answer. – Zoredache Nov 17 '11 at 0:06
