No, these should be different issues; you may have a libssl (which uses libcrypto) requiring libcrypto to be linked in, even if you only use interfaces from libssl (and that's what NEEDS_CRYPTO_WITH_SSL seem to be designed to deal with), but in this case what you have is rather imap-send using the libcrypto interfaces _as well as_ the libssl interfaces. I have blogged a detailed analysis of the problem, if you wish to see the details: http://blog.flameeyes.eu/2010/11/26/it-s-not-all-gold-that-shines-why-underlinking-is-a-bad-thing -- Diego Elio Pettenò — “Flameeyes” http://blog.flameeyes.eu/ If you found a .asc file in this mail and know not what it is, it's a GnuPG digital signature: http://www.gnupg.org/
