error installing php-4.1.1 --with-gd

Hi there! I tried to install php-4.1.1 on my linux system with apache server. "Configure" worked without error (configure-options see below), but during "make install" there was the error described below. The previous installation of php-4.0.4pl1 (configured with the same configure-options) worked fine. None of the other components (gd, zlib, jpeg, libpng) were changed since installation of php-4.0.4pl1! Can anybody help me? Do you have any hints? Thank you very much!!
