Suspected problem with /libexec/ld-elf.so.1

[Gregory Nou]

Hi,

I'm experiencing lots of weird problems since my last cvsup (yesterday)
Everything I have installed using packages or sources after the cvsup 
doesn't work, exiting with weird error messages like for example:
% pdflatex rapport.tex
zsh: exec format error: pdflatex
or
% texi2pdf rapport.tex
pdflatex: 2: Syntax error: ")" unexpected
/usr/local/bin/texi2dvi: pdflatex exited with bad status, quitting.

and also :
/libexec/ld-elf.so.1: some_lib_here: unsupported file layout

% xpdf
/libexec/ld-elf.so.1: /usr/local/lib/libt1.so.5: unsupported file layout
% kile
/libexec/ld-elf.so.1: /usr/X11R6/lib/libqt-mt.so.3: unsupported file layout


Is someone experiencing the same problem ?
