(Although the title says "unable to compile", but the error message above
indicates that you actually succeeded in compile and did 'make install',
and that the vim giving you the message was the one you built and installed
successfully. With this understanding, I'm going to write this to you.)
First of all, check which libluajit the vim is linked against.
$ ldd /path/to/your/vim
If the vim is indeed linked against libluajit in /usr/local/lib, try this
on the command line:
$ LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH /path/to/your/vim
If it doesn't issue any error message, there're two different options you
have.
(1) Add the following line
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
to your ~/.profile, ~/.bashrc or whatever file your login shell reads at
initialization. You will need to change the line if you use a login shell
other than bash, of course.
(2) (If you can exercise the root privilege)
Open /etc/ld-so.conf with Vim, and add the following line
/usr/local/lib
to the file. Save it and quit the editor.
Then, run
$ ldconfig
to update the cache for the dynamic loader.
After you do either (1) or (2),
$ vim
should run without any error.

That's the most weird thing. If there's no such a library in /usr/lib,
the linker is supposed to issue an error and the configure script aborts
due to that.
Did you try this?
$ ./configure --with-lua-prefix=/usr/local <other options>
If neither of the ways I mentioned above works for you, and you didn't try
that yet, give it a try and see if that works for you.
It looks like is saying that it can find luajit-5.1 lib in /usr/lib but it
