put the line: /usr/local/lib

in /etc/ld.so.conf and run ldconfig (as root)

I did that, but to no avail: what next?

[wade@transport Gnu]$ cat /etc/ld.so.conf /usr/X11R6/lib /usr/lib/qt-3.2/lib /usr/local/qt/lib /usr/local/lib /usr/local/src/glut-3.7/lib/glut [wade@transport Gnu]$ sudo ldconfig [wade@transport Gnu]$ ls /usr/local/lib | grep GL libGL.so libGL.so.1 libGL.so.1.5.060000 libGLU.so libGLU.so.1 libGLU.so.1.3.060000 libGLw.so libGLw.so.1 libGLw.so.1.0.0 [wade@transport Gnu]$ ./configure --with-avi --with-quicktime --with-mpeg3 --with-gltt --with-glut --with-ieee1394 --enable-mmx loading cache ./config.cache HEAD: /usr/include /usr/local/include ../../../GemLibs/ LIBS: ../../../GemLibs/ /usr/local/lib /usr/local/src checking host system type... i686-pc-linux-gnu Configuring for Gem.pd_linux checking for gnu make... yes checking for c++... c++ checking whether the C++ compiler (c++ ) works... yes checking whether the C++ compiler (c++ ) is a cross-compiler... no checking whether we are using GNU C++... yes checking whether c++ accepts -g... yes checking for gcc... gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no checking whether we are using GNU C... yes checking whether gcc accepts -g... yes checking for a BSD compatible install... /usr/bin/install -c checking whether make sets ${MAKE}... yes checking for sh... sh checking how to run the C preprocessor... gcc -E checking for X... libraries /usr/X11R6/lib, headers /usr/X11R6/include checking for dnet_ntoa in -ldnet... no checking for dnet_ntoa in -ldnet_stub... no checking for gethostbyname... yes checking for connect... yes checking for remove... yes checking for shmat... yes checking for IceConnectionNumber in -lICE... yes checking for MMX... checking MMX found...
