Distro swap: compile can't find -llua

Just swapped from Kubuntu 11.04 to Ubuntu 11.10, new install on a different drive, tried to build mudlet from the git repository and ran into this:
/usr/bin/ld: cannot find -llua
collect2: ld returned 1 exit status
make: *** [mudlet] Error 1
Am I missing some dependency I'm not aware of? Any help would be appreciated. Not seeing what I'm missing here.

Compile How-To
You probably need to install liblua-5.1-dev package.

Checked that for dependencies before I started, also installed liblua5.1-dev already. Went looking for answers and the only enlightening info I've found is that someone who had the same problem on a different program indicated I needed to have a /usr/lib/liblua5.1.a and/or a /usr/lib/liblua.a , yet I have neither. Afraid I'm not familiar enough with the lua libraries to know if that means anything though.
EDIT: Checked the other drive, sure enough, this one's missing the liblua5.1.a the other one has. Any ideas?

Tried forcibly reinstalling, couldn't find any broken dependencies or missing libraries, hand-scanned every single lua package I could find, can't find the missing link. Caught one reference to a "cpp-dev trick", but no further detail than that, and nothing I could pin down. Would love any suggestions anyone could provide on this one.
EDIT: For now, installed the mudlet package via apt-get. Not necessarily happy with that option, but for now it'll do. Though I do find it amusing I get a segfault crash when I try to connect to the default-host profile.

Already did at multiple stages. No dice.

Not sure then, I'd post on askubuntu.com

I just ran into this last night when I did the upgrade. I don't know the underlying reason, but the simple fix is to do:
ln -s /usr/lib/x86_64-linux-gnu/liblua5.1.so /usr/local/lib/liblua.so
Adjust x86_64-linux-gnu to whatever path is appropriate for your system (this is a 64bit version of Ubuntu).

Aha! Thanks a ton. That did the trick beautifully. At first I was afraid doing "make -j7" messed it up and recloned the whole damn thing out of paranoia. And yeah, same exact directory here, Ubuntu 11.10 x64.

The qmake project file tries to find the library there, it is probably should look for the header files.
If I knew qmake better, I would get it to use pkgconfig to look for both, but I'm not sure how to do it conditionally.
