The first try is always with the undecorated name. It fails here,
which is to be expected.

The second try is with the stdcall decorated name. This clearly
matches the name you gave:
[1510](sec 1)(fl 0x00)(ty 20)(scl 2) (nx 0) 0x000154d0 _apr_env_get@12
So, either "e:\LIBAPR-1-0.DLL" is a different DLL than what you've
dumped, or something else is going on. IOW: I don't think LuaJIT
is at fault here.
BTW: It looks like you're using a virtual drive in a VM, probably
a mounted Linux host file system. This is known to fail in some
cases. E.g. most installer EXEs only run when started from a
'real' drive (this can be a VM container, too, but not a network
drive). Try copying the DLL to the Windows drive in the VM.
