So there you are, automagic dep on libevent, if it's installed. =:^( Meanwhile, if I ebuild prepare and then run the configure --help, I see this: [snip] Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --without-getaddrinfo compile without getaddrinfo function --without-ipv6 compile without ipv6 --without-libevent compile without libevent [snip] So it's a configurable option. Gentoo's ebuild simply doesn't (yet) take advantage of that. TIA. =:^)

Thanks for filing this bug. I'm at FOSDEM at the moment but will take a look when I get round to it.
(In reply to Patrice Clement from comment #2) > Thanks for filing this bug. I'm at FOSDEM at the moment but will take a look > when I get round to it. Bump? No undue rush but... well I don't think FOSDEM is two months... so as I'm going thru my open bugs ATM, I'm just wondering based on the comment if this fell thru the cracks and you need a reminder. No problem if you're snowed under ATM, tho; it's a "should fix" but not urgent as the symptoms are easily resolved manually. In any case, thanks for the quick initial reply and ACK (or even NACK were it more appropriate). That doesn't help with the technical bug, but it definitely eliminates the "if a bug is filed and nobody responds, did it actually ever get filed?" /social/ bug all too common on many (happily mostly non-gentoo/upstream, from my experience) projects. =:^) Duncan
I hitted this yesterday too ;)
