Difficult question. You might want to ask debian-legal or get the
license of the main program clarified to allow it. Here's what the
FSF has to say:

| requirements for the licenses of a plug-in?
| A: It depends on how the program invokes its plug-ins.
| If the program dynamically links plug-ins, and they make function
| calls to each other and share data structures, we believe they form
| a single program,
| This means
| the plug-ins must be released under the GPL or a GPL-compatible free
| software license, and that the terms of the GPL must be followed
| when those plug-ins are distributed.
Also see  concerning the OpenSSL/GPL incompatibility. This is
perhaps a strange edge case because the interfaces provided by
libcurl-openssl and libcurl-gnutls are not all that different.
Luckily, that gives an easy way out: does the plugin work when built
Hope that helps,
