I've already had a look last week-end, but I've not found a fix yet.

The error message

configure: error: cannot determine current directory

is the same that I was getting before patching the file

ghc-7.8.4/utils/ghc-pwd/dist-install/build/tmp/ghc-pwd

in the binary distribution for x86_64.

ldd on that file for the i386 executable gives (from a Debian shell):

All haskell libraries are found with the help of the ghc build system and I
patch the hardcoded interpreter with

(system* "patchelf" "--set-interpreter"
  (string-append (assoc-ref inputs "libc")
                 (glibc-dynamic-linker)))

I'm not sure about the difference between "linux-vdso.so.1" and
"linux-gate.so.1".  As far as I understand they are the gateway into the
kernel for system calls, but have zero experience with that.

Any help would be appreciated.
