Mandriva 2006, gcc si libblas.so stricat

Am avut Mandriva LE 2005 pe doua calculatoare... Au mers super!
Pe unul din ele am inceput trecerea la 2006 progresiv: 2006 RC1, 2006 RC2 si acum 2006 Official cu un net-install (comanda urpmi --auto-select)
Pe celalalt (calculatorul pe care stau acum) am facut trecerea la 2006 direct in Official cu un net-install in aceasta noapte... Sistemul este updatat complet la 2006 (inclusiv kernel-ul) si am o problema:

[syl@jucarie QFileRenamer]$ make
g++  -o renamer .obj/mainform.o .obj/qmake_image_collection.o .obj/moc_mainform.o   -L/usr/lib/qt3//lib -L/usr/X11R6/lib -lqt-mt -lXext -lX11 -lm
/usr/lib/gcc/i586-mandriva-linux-gnu/4.0.1/../../../crt1.o: In function `_start':
../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [renamer] Error 1

este tentativa de compilare a unui programel pe care l-am facut pe 2006 Official! Tot ce-am facut mai demult (LE2005, gcc 3.x) merge compilat pe 2006 cu gcc 4.0.1-5...
se mai observa si urmatoarea eroare:

[syl@jucarie ~]$ gcc -lblas

am reinstalat libblas si am instalat si gfortran si tot nu vrea :(
Pe net nu am gasit decat o problema perfect identica, tot in Mandriva 2006, chiar pe mailing list-ul lor, dar nu s-a raspuns inca acolo... Problema persistă şi pe gcc 3.3.6. Aveţi vreo idee?
