aRts - install fails on HPUX 11.00

Hi,
I'm trying to compile arts-1.0.4 on hpux 11.00,
so I can compile KDE 3.0.3 on it.  ./configure and gmake work fine, but
when I try to 'gmake install' I get the following  Errors:

udioiosgi.lo ../mcop/libmcop.la libartsflow_idl.la -L/usr/lib -L/usr/local/qt/lib -L/usr/local/kde/l

I have qt-3.0.5 already installed in /usr/local/qt

GNU make-3.79.1 
gcc-3.2
libtool-1.4.2
libarts-1.0.0 fails with the same errors.

have you any idea ?

thanks in advance.
