First I was running 6.3 but I upgraded to 7.0 thinking that it might of solve the problem but it didn't.  What amazes me is, I've got ubuntu installed on the same machine and it only takes 3 seconds to start, also it only takes 3 seconds to start in windows.  Evolution running like this is completely worthless.  Any ideas what might be causing this?  Please respond to my email address also.

As far I'm concerned evolution is out of my list of programs, I still have my doubts about the real reason as to why it takes so long to open.  In reality there's no real reason as to why a program will take so long to open, if that's the case evolution will loose a lot of users in the FreeBSD community.

I suspect that the patch in this PR would have greatly helped:

	http://www.freebsd.org/cgi/query-pr.cgi?pr=104877

Indeed, a casual inspection of libexec/rtdl-elf/rtld.c shows that the
SO_NEEDED lists (Obj_Entry.needed) are walked recursively. Removing
the useless entries might therefore have a dramatic impact on
performance.

Unfortunately, the affected maintainer has closed the PR, mainly
because he could not understand it. And portmgr has backed the
maintainer, mainly because of personal friendship.

With such irrational behaviours, this trend is not going to reverse
itself anytime soon:
