 http://www.haskell.org/ghc/dist/7.8.1-rc1/ghc-7.8.20140130-i386-unknown-
 solaris2.tar.bz2 has a ghc-pwd-bindist script containing

 {{{
 #!/bin/sh
 export LD_LIBRARY_PATH="libraries/directory/dist-
 install/build:libraries/unix/dist-install/build:libraries/time/dist-
 install/build:libraries/old-locale/dist-install/build:libraries/filepath
 /dist-install/build:libraries/bytestring/dist-
 install/build:libraries/deepseq/dist-install/build:libraries/array/dist-
 install/build:libraries/base/dist-install/build:libraries/integer-gmp
 /dist-install/build:libraries/ghc-prim/dist-
 install/build:rts/dist/build:$LD_LIBRARY_PATH"
 exec "utils/ghc-pwd/dist-install/build/tmp/ghc-pwd" ${1+"$@"}
 }}}

 that fails during configure under Solaris with:

 {{{

 install/build/tmp/ghc-pwd-bindist: LD_LIBRARY_PATH=libraries/directory
 /dist-install/build:libraries/unix/dist-install/build:libraries/time/dist-
