guile-www install.

[R. Clayton]

I installed guile on a debian testing system:

  $ dpkg -l guile*
  Desired=Unknown/Install/Remove/Purge/Hold
  | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
  |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
  ||/ Name           Version        Description
  +++-==============-==============-============================================
  un  guile          <none>         (no description available)
  ii  guile-1.8      1.8.7+1-2      The GNU extension language and Scheme interp
  ii  guile-1.8-doc  1.8.7+1-2      Documentation for Guile 1.8
  un  guile-1.8-doc- <none>         (no description available)
  ii  guile-1.8-libs 1.8.7+1-2      Main Guile libraries

  $

and then I wanted to install guile-www 2.26 (the latest, I believe), but ran
into this:

  ul pwd
  /usr/local/src/guile-www-2.26

  $ ./configure
  checking for a BSD-compatible install... /usr/bin/install -c
  checking whether build environment is sane... yes
  checking for a thread-safe mkdir -p... /bin/mkdir -p
  checking for gawk... gawk
  checking whether make sets $(MAKE)... yes
  checking whether to enable maintainer-specific portions of Makefiles... no
  checking for guile... /usr/bin/guile
  checking for guile-config... no
  configure: error: guile-config required but not found

  $ 

Peeking ahead in configure, it seems it will also die when it looks for
guile-tools.

  $ locate guile-config

  $ locate guile-tools

  $

This suggests that something is out of whack, but I don't know (apart from the
obvious) what it might be.  What's the explanation, and the fix?
