 }}}

 Then I do
 {{{
 rm -r libraries/bootstrapping.conf
 make clean
 }}}
 and this succeeds.

 Now I build again:
 {{{
 make
 }}}
 and get an error:
 {{{

 }}}
 But the thing is created as a file now:
 {{{
 $ ls -l libraries/bootstrapping.conf
 -rw-r--r-- 1 ggreif grp 3 Dec 18 11:17 libraries/bootstrapping.conf
 }}}
 I can recreate it manually:
 {{{
 $ rm libraries/bootstrapping.conf
 $ /home/ggreif/bin/ghc-pkg init libraries/bootstrapping.conf
 $ ls -ld libraries/bootstrapping.conf
 drwxr-xr-x 2 ggreif grp 96 Dec 18 11:23 libraries/bootstrapping.conf
 }}}

 And now `make` works...
