Hi, I'm currently trying to upgrade Debian GNU/Hurd ghc6.8.2 to 6.10.1 (and further from there, due to requirements of ghc and haddock versions), and get stuck on configuring the random-1.0.0.1 library in stage1. I have tried versions of ghc6 are 6.10.1+dfsg1-1 to 6.10.1+dfsg1-5 (the latest not requiring ghc6.10 due to haddock 2.4.2). The commands are shown below: (added the -verbose=3 parameter) cd ghc6-6.10.1+dfsg1/libraries (sorry for the missing \ due to cut-and-paste to the mailer) ( cd random && /home/srs/DEBs/ghc/ghc6-6.10.1+dfsg1/libraries/cabal-bin --verbose=3 /usr/bin/ghc6 /home/srs/DEBs/ghc/ghc6-6.10.1 +dfsg1/libraries/bootstrapping.conf configure --verbose=3 --prefix=/NONEXISTENT --bindir=/NONEXISTENT --libdir=/NONEXISTENT --libexecdir=/NONEXISTENT --datadir=/NONEXISTENT --docdir=/NONEXISTENT --haddockdir=/NONEXISTENT --htmldir=/NONEXISTENT --with-compiler=/home/srs/DEBs/ghc/ghc6-6.10.1 +dfsg1/ghc/stage1-inplace/ghc --with-hc-pkg=/home/srs/DEBs/ghc/ghc6-6.10.1 +dfsg1/utils/ghc-pkg/install-inplace/bin/ghc-pkg --libsubdir='$pkgid' --with-gcc=gcc --with-ld=/usr/bin/ld --with-hscolour=/usr/bin/HsColour --with-alex=/usr/bin/alex --with-happy=/usr/bin/happy --configure-option='--build' --configure-option='i486-gnu' --configure-option='--prefix=/usr' --configure-option='--with-ghc=/usr/bin/ghc6' --configure-option='build_alias=i486-gnu' --configure-option='CFLAGS=-g -O2' --configure-option='LDFLAGS=' --configure-option='CPPFLAGS=' --configure-option=--with-cc=gcc --with-hsc2hs=/home/srs/DEBs/ghc/ghc6-6.10.1 +dfsg1/utils/hsc2hs/install-inplace/bin/hsc2hs --haddock-options="--use-contents=../index.html --use-index=../doc-index.html" --enable-library-profiling --enable-split-objs ) && touch stamp/configure.library.build-profiling-splitting.random || touch random/unbuildable Output: ======= Creating dist (and its parents) ("/home/srs/DEBs/ghc/ghc6-6.10.1\ +dfsg1/ghc/stage1-inplace/ghc",["--numeric-version"]) /home/srs/DEBs/ghc/ghc6-6.10.1+dfsg1/ghc/stage1-inplace/ghc is version 6.10.1 ("/home/srs/DEBs/ghc/ghc6-6.10.1\ +dfsg1/utils/ghc-pkg/install-inplace/bin/ghc-pkg",["--version"]) /home/srs/DEBs/ghc/ghc6-6.10.1\ +dfsg1/utils/ghc-pkg/install-inplace/bin/ghc-pkg is version 6.10.1 ("/home/srs/DEBs/ghc/ghc6-6.10.1\ +dfsg1/ghc/stage1-inplace/ghc",["--supported-languages"]) Reading installed packages...

I also tried to escape some of the variables in the gkc-pkg shell script but without any luck. Anybody can help me here??
