[gentoo-user] jpeg compilation error

[Arnau Bria <arnau@emergetux.net>]

Hi,

I was doing my weekly world update, when my system stopped the update
at this ebuild:
1149848117:  === (11 of 42) Compiling/Merging 
(media-libs/jpeg-6b-r7::/usr/portage/media-libs/jpeg/jpeg-6b-r7.ebuild)

with next error:

creating Makefile
creating jconfig.h
./libtool-wrap --mode=compile i686-pc-linux-gnu-gcc -march=pentium4 -O2 -pipe -fomit-frame-pointer -mtune=i686  -I. -c ./jcapimin.c
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'
make: *** [jcapimin.lo] Error 1

On a first google and gentoo forums search[1],  I found that emerge
-oneshot libtool will solve my problem. But, could someone explain me
why "do not add the packages to the world profile for later updating"
will solve my problem?

The other solution I found [2], is emerge libtool, but, isn't it what
emerge -uD world is trying to do?

PS: sorry for not wrapping long lines, but I thought wrapping first one
could generate confusion, and I don't know if I have to cut links.

Cheers!
