Never heard of Ubuntu, I presume it is a flavour of Unix.

You need to either:

(1) Build your Exim binary such that it knows where to find the library at
run time. The usual way to do this is to set

LD_RUN_PATH=/path/to/mysqllibs

in the environment before building. (At least, this works if you are using
GNU gcc and binutils)

(2) Alternatively, you can configure your Unix loader so that
/path/to/mysqllibs is in your permanent library path.

For Solaris: See "man crle"
For FreeBSD: See "man ldconfig"
For Linux: I think it goes in /etc/ld.so.conf (it's been a while since I
used Linux)

Otherwise, as you've found, the library won't be found unless you set the
LD_LIBRARY_PATH environment variable at runtime, and to be sure this always
happens you'd need always to start exim from a script, which is annoying.
And then, when Exim re-execs itself, I'm not sure if this environment
variable is kept or not, so it's a dangerous way to work anyway.
