I try to install prelude db with mysql database but I met a bug :
checking for libprelude - version >= 0.9.9... no

• Could not run libprelude test program, checking why...
• The test program compiled, but did not run. This usually means
• that the run-time linker is not finding LIBPRELUDE or finding the wrong
• version of LIBPRELUDE. If it is not finding LIBPRELUDE, you'll need to set your
• LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
• to the installed location Also, make sure you have run ldconfig if that
• is required on your system ***
• If you have an old version installed, it is best to remove it, although
• you may also be able to get things to work by modifying LD_LIBRARY_PATH ***

When I type vi /etc/ld.so.conf I had : include /etc/ld.so.conf.d/*.conf and in other ocnfiguration files,

1. libc default configuration
   /usr/local/lib

so I try to undestand the error but I deseaspear. Can you help me please ?
