Thanks but i just installed them and i still get the same error
Maybe the filename is different. Look for it by running:
locate libcurl.so
Maybe you don't have
/usr/lib/libcurl.so.4 but
/usr/lib/libcurl.so.4.0.1 or so (with more detailed version). If that's the case you can make a symbolic link on it by running
sudo ln -s /usr/lib/libcurl.so.4.0.1 /usr/lib/libcurl.so.4
(change the version to your's)
I hope this help.
