VirtualBox 4.1.20_0, fail to find libcrypto

[xl64100@…]

I Can't upgrade virtualbox (was the same with 4.1.18 but I waited to see if it would be solved in next macports updates).

I get this log :

sudo port clean virtualbox
--->  Cleaning virtualbox

sudo port upgrade virtualbox

To report a bug, follow the instructions in the guide:

And in the main.log (attached) :

:info:configure Checking for ssl: 
:info:configure   libcrypto not found at -I/opt/local/include /opt/local/lib/libcrypto.dylib /opt/local/lib/libssl.dylib or openssl headers not found

Thanks for any help.

Oups, didn't preview. How can I edit it to make it more readable ?

Tried to force rebuild openssl as I assumed it was the one providing the libcrypto library but this had no effect...
