I'm guessing I did something not quite right in the installation, but without more information, there's no way to know how to fix it.

Signal 11 is a segfault, i.e. something goes very wrong.
It's hard to say anything definite at this point, but are you sure that 
the mpicc and lamboot you use belong to the same version of lam?
If there is an old lamd (say, 7.1.1) hanging around, using a 7.1.2
mpicc might lead to a crash.
