Re: slow startup for xemacs on Darwin

If I build using your flags it works for me. So it seems that linking in the wrong X11 libs is the problem here and it's a MacPorts issue.

On Mac OS X, this is the weird name that DISPLAY gets set to to get direct rendering. It does not work to set DISPLAY to ":0". I don't want to use DISPLAY="rcmac.llnl.gov:0" because that will cause it to hit the NIC instead of go straight to the card for rendering. >>> >>> Hmm... Just checked on my Mac. The display name is set to "/tmp/launch-TkSI95/org.x:0". That's a really curious format for a "local" display string. On my Mac, when I run "xterm" under X, that file is a local socket. A local transport mechanism like that should really not have a colon in it. This appears to confuse some software into thinking it is a "hostname:0" display variable format, so it tries to lookup "hostname". >>> >>> I still agree with others that your DNS is broken; if it cannot come back and tell you quickly that the hostname "/tmp/launch-gcmVOm/org.macosforge.xquartz" can't be resolved, its broken. >>> >>> However, I wonder why xemacs is trying to resolve this address. Local X applications on my system don't appear to do a DNS lookup when I use a display name like "/tmp/foo/bar/baz:0", so why does xemacs? Is it possible that either XEmacs is not using the locally installed XLIB library?
