~# emerge --info
Portage 2.1_rc1-r2 (default-linux/x86/2005.1, gcc-3.4.6, glibc-2.4-r3,
2.6.17-rc4-mm1 i686) 

There is my problem.I installed gcc-4-02 whithout emerge thinking that
under /usr/local it was in a safe place (not in root PATH).
Now when i untar and compile  LVM2.2.02.05.tgz as root it uses gcc-3.4.6
and everything is OK but as user it uses gcc-4.0.2 and it fails!
Although emerge --info says gcc-3.4.6 , it fails because it uses
gcc-4.0.2 ( the error messages are exactly the same ).
Now, why it says one thing and does another and why 4.0.2 fails where
3.4.6 succeeds is another question.I noticed the presence of a file
libdevmapper.h under /usr/local/lib/gcc that was quite different from
/usr/include/libdevmapper.h. I replacing it with a symlink and the
emerge succeeded. But is that safe? Anyway,for me the lesson is clear:be
carefull before installing something outside portage control!

Thankx!
