Because of features I switched my TeX distribution from teTeX@Gentoo to TeXLive which installs its binaries in /usr/local/bin/texlive/2005/bin/i386-linux/ and this was added to $PATH in /etc/profile. All executables work. I unmasked auctex-11.81 and it emerges fine, but with USE=+preview-latex when configuring preview-latex it stops with not finding the latex executable. After a bit of investigation I found out that configure can't find any executable (be it kpsepath, kpsewhich, tex, pdflatex...), hardcoding paths in auctex-11.81/preview/configure helps a bit, but I cannot get a successful run. Even defining the PATH variable locally in preview/configure helps to a certain point (at least the executables are found). With teTeX 2.0.2-r5 the installation works. ------------emerge --info-------------- fauli@luna ~ $ emerge --info Portage 2.0.53 (default-linux/x86/2005.1, gcc-3.3.6, glibc-2.3.5-r2, 2.6.14-gent oo-r5 i686) ================================================================= System uname: 2.6.14-gentoo-r5 i686 AMD Athlon(tm) XP 2500+ Gentoo Base System version 1.6.13 ccache version 2.3 [enabled] dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.20 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=athlon-xp -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share /config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/ mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/splash /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=athlon-xp -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig candy ccache distlocks sandbox sfperms strict" GENTOO_MIRRORS="ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo/" LANG="de_DE@euro" LC_ALL="de_DE@euro" LINGUAS="de" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.informatik.rwth-aachen.de/gentoo-portage" USE="x86 3dnow 3dnowext X Xaw3d a52 acpi alsa apm artworkextra asf audiofile avi bash-completion berkdb bidi bitmap-fonts bootsplash bzip2 cdda cddb cdparanoia cdr cracklib crypt css cups curl custom-cflags dbus dga directfb divx4linux dts dvd dvdr dvdread eds emacs emboss encode esd exif expat fam fbcon fdftk ffmpeg f lac foomaticdb fortran ftp gb gcj gdbm gif glut gnome gphoto2 gpm gstreamer gtk gtk2 gtkhtml hal howl icq idn imagemagick imap imlib ipv6 java javascript jikes jpeg junit lcms ldap leim libg++ libwww mad maildir matroska mbox mikmod mime mm x mmxext mng mono motif mp3 mpeg mpeg2 mule ncurses nls nocardbus nptl nptlonly ogg oggvorbis opengl pam pcre pdflib perl plotutils png ppds preview-latex print python qt quicktime readline recode samba sdk slang spell sse ssl svg svga tclt k tcpd theora tiff truetype truetype-fonts type1-fonts udev usb vcd videos vorbi s win32codecs wmf wxwindows xine xinerama xml xml2 xmms xosd xv xvid zlib lingua s_de userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LDFLAGS ------------------output-------- Calculating dependencies ...done! >>> emerge (1 of 1) app-emacs/auctex-11.81 to / >>> md5 files ;-) auctex-11.81.ebuild >>> md5 files ;-) files/digest-auctex-11.81 >>> md5 files ;-) files/auctex-11.81-configure.diff >>> md5 files ;-) files/50auctex-gentoo.el >>> md5 src_uri ;-) auctex-11.81.tar.gz >>> Unpacking source... >>> Unpacking auctex-11.81.tar.gz to /var/tmp/portage/auctex-11.81/work * Applying auctex-11.81-configure.diff ...

Sorry, we cannot support packages that are not in portage.
I forgot to add: A dry run with the same configuration options in my home-directory as called by the ebuild works perfectly fine with all executables found: ./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-build-dir-test --with-auto-dir=/var/lib/auctex --with-lispdir=/usr/share/emacs/site-lisp --build=i686-pc-linux-gnu So maybe you have some good resources where debugging ebuilds is described?
Sorted it out via the ebuild tool, thank you
