Running binary with different libraries

Hi,

is it possible to start apps link to a library to use library from a
specified location?
For example I have an app which needs libssl.so.0 By default this
library is in /usr/lib or /usr/local/lib depending on the distro. For
testing purposes I have compiled openssl into /usr/local/openssl-0.9.7m/
This way I'm sure I don't screw up something running.

But how can I force an app when I exec it to use the .so file from
/usr/local/openssl-0.9.7m/ ?
When I specify the path in an environment var LD_LIBRARY_PATH output
from ldd %mybinary% show the right path. But once running it has the
library open from the default location.

How can I 'force' it to use the library from the right location other
than compiling the app static and messing with ld.so.conf and ldconfig.


Regards,
