Licensing question

[Elías Alejandro <ealmdz@gmail.com>]

Hi all,
I want your advices about a package that requires in its new 
upstream release, as build dependency: libcurl4-openssl-dev
Previous releases was built with libcurl4-gnutls-dev and packaging
under GPL-3.
So, If there any licence issue if it is compiled with libcurl4-openssl-dev
instead of libcurl4-gnutls-dev and packaging under GPL-3?
I was reading [1], point 28 but I'm not sure because it isn't directly
the OpenSSL library.
