/usr/local/lib is not properly supported

[Damjan Jovanovic]

Take just about any tarball and do the usual ./configure && make && make install. It will almost certainly refuse to work because it can't find its libraries.

/usr/local/lib needs to appear in /etc/ld.so.conf, or LD_LIBRARY_PATH needs to be set in /etc/profile by default.

I concur. Using Feisty Fawn, /usr/local/lib is still not a part of the ld.so.cache.

Usual Linux semantics is the distro packages go into /usr/lib while third party builds go in /usr/local/lib.

Creating and adding /usr/local/lib to /etc/ld.so.conf.d/local.conf and rerunning ldconfig will solve this problem, but this isn't setup by default.

This was actually fixed in the version of glibc that shipped with Gutsy.

/usr/local/lib is defined in /etc/ld.so.conf.d/libc.conf
