Bugzilla Bug 73328

As am-wrapper was unmasked recently I should now emerge all kind of versions of
automake. I've already installed several versions of autoconf, and by default
version 2.13 is chosen, which is too old for automake-1.8.5-r2.
Therefore the build dies with:
===
checking whether autoconf works... no
configure: error: The installed version of autoconf does not work.
    Please check config.log for error messages before this one.

!!! ERROR: sys-devel/automake-1.8.5-r2 failed.
!!! Function econf, Line 449, Exitcode 1
!!! econf failed
===
Related? bug:
bug #71411

If i skip this build, and continue my emerge with
emerge --resume --skipfirst
the following ebuilds have more or less similar errors (in case these ebuilds
need to be fixed):
sys-devel/automake-1.6.3
sys-devel/automake-1.7.9
I'll note the others (currently compiling), in case they are necessary.

Reproducible: Always

if you `env WANT_AUTOCONF=2.5 emerge automake` does it work ?

I tried (under zsh):
env WANT_AUTOCONF=2.5 emerge --oneshot '=sys-devel/automake-1.8.5-r2'
WANT_AUTOCONF="2.5" emerge --oneshot '=sys-devel/automake-1.8.5-r2'
and none worked

also:
root@basil ~ $ WANT_AUTOCONF="2.5" autoconf --version
Autoconf version 2.13

so I would say: no

I wished I would not have tried "emerge -a libtool" because now I can't
reproduce the error with "emerge autoconf" and "emerge automake". They require
each other, better said:

the automake configure (or the like) *requires* autoconf >= 2.5

"emerge autoconf" tries to build automake *before* building autoconf

-- if I remember right.

that doesn't seem to be the problem here, as both versions of autoconf are
correctly installed (at least I hope so). The newer one is just not used.

Im just installing, from 2004.3 with stage2. I changed some option (among other
stuff "emerge portage" called directly instead of within "emerge system"?? or
was it the use-nptl?), fiddled around a bit and ended up in everything being
rebuilt: ebuilds like sed, patch and others were then done for "emerge system";
iirc this was not contained in "emerge -pretend system" before... :-/ :-)

anyways, you seem to have a possible workaround with "emerge -a libtool", as
proposed in bug#71411, but it might give You a lot of compiles... is that "-a"
for "all"?

emerge -a == --ask (just more efficient as emerge -p == --pretend).
But this doesn't solve my problem, as Autoconf is already installed here. 

florian: can you `emerge autoconf-wrapper` and see if `WANT_AUTOCONF=2.5
autoconf --version` works ?

reemerging the ac-wrapper fixed the whole problem. Unfortunately I can't tell
now, why, how and who modified the /urs/lib/misc/ac-wrapper.sh.
When I reemerged, I got the following line:
>>> Safely unmerging already-installed instance...
--- !mtime obj /usr/lib/misc/ac-wrapper.sh
I'm not sure, but doesn't that mean, that ac-wrapper.sh had been somehow
modified outside portage?

did you emerge autoconf before i unmasked it ?

while it was masked i made changes to it to fix bugs but didnt rev bump it ...

no. I'm using ~x86 (obviously), but I haven't unmasked anything recently (and
certainly not autoconf).

autoconf-wrapper-1-r1 now in portage
