I downloaded and installed MySQL Community Server 5.5.15 from http://dev.mysql.com/downloads/mysql/5.5.html
Using CPAN, I then tried to install DBD::mysql on a fresh install of OS X Lion and was presented with an error saying it was unable to load the library.
# Error: Can’t load ‘/private/var/root/.cpan/build/DBD-mysql-4.019-H1RD6j/blib/arch/auto/DBD/mysql/mysql.bundle’ for module DBD::mysql: dlopen(/private/var/root/.cpan/build/DBD-mysql-4.019-H1RD6j/blib/arch/auto/DBD/mysql/mysql.bundle, 2): Library not loaded: libmysqlclient.18.dylib
# Referenced from: /private/var/root/.cpan/build/DBD-mysql-4.019-H1RD6j/blib/arch/auto/DBD/mysql/mysql.bundle
After a bit of searching, I came across http://probably.co.uk/problems-installing-dbdmysql-on-os-x-snow-leopard.html which although it’s for Snow Leopard has a very similar error and the fix works great on Lion as well.
$ sudo install_name_tool -id /usr/local/mysql-5.5.15-osx10.6-x86_64/lib/libmysqlclient.18.dylib /usr/local/mysql-5.5.15-osx10.6-x86_64/lib/libmysqlclient.18.dylib
$ otool -D `mdfind libmysqlclient.18.dylib`
After running the name_install command, DBD::mysql built and tested correctly.
(I’m still searching the web – but as I saw your posting here…)
I have mysql-5.5.14-osx10.6-x86 (although interestingly enough, when I run mysql and do ‘? version’ it comes back with 5.5.16-standard), which I’ve gotten that up and running on Lion and have been using it without any significant problems.
So I went to my Perl installation (it had been 5.8.3 but I was running into all sorts of issues with it, so I downloaded fresh source and built it myself – version 5.14.1) and tried to do a ‘cpan’ installation of DBD::mysql (after having done an installation of DBI) – and it kept failing, so I went to the actual build directory. ‘make’ seems to be fine, but it dies when trying to do a ‘make test’:

blib/lib/DBD/mysql.pmI tried the steps you mentioned with install_name_tool and otool, and though they seemed to work (no errors shown) – they didn’t seem to resolve the issue I’m having.
