>Description:
The problem is that ld can not find libraries in /usr/local/lib even if
ldconfig can. For example:
ldconfig -r | grep event
107:-levent-1.4.3 => /usr/local/lib/libevent-1.4.so.3
108:-levent_core-1.4.3 => /usr/local/lib/libevent_core-1.4.so.3
109:-levent_extra-1.4.3 => /usr/local/lib/libevent_extra-1.4.so.3
The last rows of the next printout is intersesting because they show that
/usr/local/lib is not even searched by ld:
ld --verbose -l event
GNU ld version 2.15 [FreeBSD] 2004-05-23
Supported emulations:
elf_i386_fbsd
elf_x86_64_fbsd

ld: cannot find -levent
>How-To-Repeat:
I have 2 newly installed FreeBSD 8 systems with the latest and greatest updates
and libevent installed from ports and none of the systems can find any libs in
/usr/local/lib. If you search the FreeBSD community forum you can find many
similar cases all involving problems with finding libs in /usr/local/lib.
