Comment (by nushio):

 I hit the same issue while installing {{{singletons}}} package using GHC
 7.7.20131217 on

 {{{
 Linux nusid 3.8-2-amd64 #1 SMP Debian 3.8.13-1 x86_64 GNU/Linux
 }}}

 The tail of the installation message was:

 {{{
 Loading package mtl-2.1.2 ... <command line>: can't load .so/.DLL for:
 libHSmtl-2.1.2.so (libHSmtl-2.1.2.so: cannot open shared object file: No
 such file or directory)
 Failed to install singletons-0.9.3
 cabal: Error: some packages failed to install:
 singletons-0.9.3 failed during the building phase. The exception was:
 ExitFailure 1
 }}}

 The temporal solution to this was (as hinted by Feuerbach) to set
 {{{shared: True}}} in my {{{~/.cabal/config}}} file, and then to {{{cabal
 install mtl --force-reinstall --reinstall }}} .
