Hi Srinivas,
Why is this an issue? Is it for an application?
From a library point of view, the version installed on the system
should make no difference unless you are using deprecated (old) or brand
new routines in the library. This should not be an issue, especially as
you are talking
Er... no.
If you want to install two separate versions on the same machine, you
MUST put them in separate --prefixes.
You also need to make sure that each compilation of Apache refers to
the correct prefix. (You cannot rely on the system Doing The Right
Thing, here, you must compile your own.)
