When Eta tries to build and install the dependency, 'statistics:0.15.2.0', it suddenly went into panic while building the library for math-functions-0.3.3.0.

Eta then exited the build process with an exception.

I am afraid the package contains foreign calls to c functions (ccall unsafe...)
One way to make the package work with eta is replace the c calls with java ones and upload the patch to the set of patches in eta-hackage https://github.com/typelead/eta-hackage
