libtool & shared libraries

Hi!
When I try to ./configure any library on QNX 6.1 box I’ve get a message
" libtool does not support shared libraries"
I had tried to update libtool to 1.4.2 with patch from
http://mail.gnu.org/pipermail/libtool/2001-July/005170.html
When I try to configure libtool - all just fine, “libtool --features” also
says, that libtool support shared libraries.
But when I try to build any other library/application - it say’s that
libtool does NOT support shared libraries.
What am I do wrong? How to fix this issue?

Regards,
Sergey Sobolev
