Description:   Opened: 2006-04-30 00:32 0000 
When preview-latex use flag is set, app-emacs/auctex should probably dep on
app-text/dvipng.  Its not strictly necessary but apparently is much faster then
using dvips/ghostscript.

I forgot to mention that the reason I mention is that tetex-3.0_p1-r3 no longer
installs dvipng, so in the past we didn't need auctex to dep on dvipng

Thanks for the note. Committed to portage.

ppc, ppc-macos, ppc64 people, please keyword the dependency, app-text/dvipng
and then keyword app-emacs/auctex-11.83.ebuild.

this won't pass configure for me (PPC64):


checking for Emacs prefix... cat: ./conftest-20239: No such file or directory
""
checking if Emacs is recent enough... cat: ./conftest-20239: No such file or
directory

configure: error: This package requires at least Emacs version 21.1  Aborting!

!!! Please attach the following file when filing a report to bugs.gentoo.org:
!!! /var/tmp/portage/auctex-11.83/work/auctex-11.83/config.log


this happens with version 11.83 and 11.82. can someone confirm this?

looks like a regression wrt the configure patch. i'll check that out and get
back to you

Works fine for me here on ppc64, but I've got app-editors/emacs-cvs-22.0.50.

Added ~ppc.

I can confirm this: auctex fails if emacs is installs but installs just fine if
emacs-cvs is installed. (only tested on ppc64)

 I am thinking about patching Emacs detection from AUCTeX' build system. 
ppc64, could you try 11.84?  If it fails, too, please apply this patch and try
again.

ppc-macos, please consider the keywords on app-text/dvipng and app-emacs/auctex
or drop them entirely.

------- Comment #12 From Fabian Groffen 2007-03-17 23:32:55 0000 ------- 
I see you removed it yourself.

kind of late this answer, but the patch does solve this problem.

ppc64, 11.84-r1 has the patch and should work for you.  A test plan for AUCTeX
is found in bug #154240.  If AUCTeX works, dvipng is fine, too.

------- Comment #15 From Markus Rothe 2007-04-09 09:22:43 0000 ------- 
thanks for the patch! works fine on ppc64 now. added ~ppc64

last arch CC'd and auctex now depends on dvipng -> marking as FIXED
