Try the suggestions of bowei_99, but if you really want to nail down this problem, continue reading :)

Looking at the initial error message again, I see this important thing:

libapreq2.so.2: cannot open shared object file: No such file or directory

Let's check if your httpd binary has all libraries:

ldd /usr/sbin/httpd
[download]

And check that there are no missing libraries in the output of ldd. BTW, is /usr/sbin/httpd your correct Apache binary?

Even if ldd of httpd locates all libraries, find where your libapreq2.so.2 is and add it to your LD_LIBRARY_PATH environment variable.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/of/your/libapreq2
[download]

Then try the "make test" again.

Note: setting the LD_LIBRARY_PATH variable is not recommended, I'm suggesting it here just for the sake of debugging.
