The problem still persists!

I have found a workaround:
# env LD_PRELOAD=/usr/local/lib/libpng.so.5 /usr/local/etc/rc.d/apache22 restart
I find the implications deeply troubling. Note that ldd has no problems
locating the library:
# ldd /usr/local/lib/php/20060613/gd.so
/usr/local/lib/php/20060613/gd.so:
...
libpng.so.5 => /usr/local/lib/libpng.so.5 (0x80120d000)
...
So why does the apache module fail to load it? Why do I have to force
the runtime linker to do so?
