The problem is that the currently distributed libphobos2.so is linked against a GnuTLS version of libcurl (libcurl-gnutls.so.4) but Fedora only ships with an OpenSSL version of that library.

Yes, this is the issue Jordi Sayol has been talking about. We couldn't find an acceptable solution (Jordi suggested making a custom build of libcurl on Ubuntu, while that works, I regard that as impractical for 3rd parties wanting to fork/build phobos from the repository).

Why do we want to link to the GnuTLS version? Can't we link with the system default or something like that? I find this page describing some differences between the SSL libraries supported by libcurl.

It assumed that GnuTLS is default version on Debian but this page suggest it's
not.
http://packages.debian.org/search?keywords=libcurl3
So we need to find out why we're linking against the wrong library.

Problem does not exist on Arch Linux as it does not use .zip and uses git tag instead.

libcurl4-dev is a virtual package provided by
  libcurl4-openssl-dev
  libcurl4-nss-dev
  libcurl4-gnutls-dev

So this issue can be solved by installing replacing libcurl4-gnutls-dev with libcurl4-openssl-dev on the build machine.

This is a known issue.
On Debian, Ubuntu, etc., all curl libraries has "versioned symbols", which are
not properly handled by others Linux systems like Fedora, OpenSUSE, etc., where
their curl libraries do not have any versioned symbol.

libphobos linked on Debian includes libcurl versioned symbols which will not work on Fedora, but libphobos linked on Fedora will work on Debian.

So there are two possible solutions:

- Link libphobos on a system like Fedora (libcurl without versioned symbols).

- Install a non versioned symbols curl libraries on Debian, and resulting phobos library will work on almost every Linux system.

I just offered Walter a personalized deb package which installs Fedora's curl libraries (non versioned symbols) on Ubuntu (until now Linux building process was done on Ubuntu). These libraries will only be used to link libphobos, and resulting libraries will works on almost all Linux systems. This deb package will NEVER be publicly offered because is NOT needed by any user.

Someone knows another way to fix this? Removing the lubcurl dependency on libphobos in not an option, at least by the moment.

This is correct because Arch packages links its own libphobos on Arch, and don't use the libphobos from release zip archive.

In other words, libphobos compiled/linked in an Specific Linux system will always work on this specific Linux system.

This is not correct. All curl libraries on Debian like systems has versioned symbols, source of this problem.

That is exactly what I have meant. Why do we insist on using the same .zip archive built on Debian-like system everywhere? Native packaging does avoid this problem and scales much better.
