Thanks for the pointer to the openssl-0.9.8 source. In hindsight, I realize I could read the .info file and do a bit of deduction, but with there not being an openssl-0.9.8 binary extension in 4.x, I had ruled out that avenue.
Is there a general algorithm that can translate from the binary extension name (libssl-0.9.8 in this case) to the name of the source (openssl-0.9.8 in this case)?
I would think it would be helpful if perhaps a line could be added to the info file for cases like this where the names differ--something like this:
Source-name: openssl-0.9.8
It appears lighttpd-nodeps is another case where the source has a different name from the binary extension.
