 The file CT_Analytic_Exact_Calc.cc takes more than 30 minutes to build on
 Shelob, and the build process is thus aborted by the operating system:

 {{{
 COMPILING arrangements/CTThorns/CT_Analytic/src/CT_Analytic_Exact_Calc.cc

 (code 1)
 }}}

 I've looked at the source code. It seems Kranc-generated, with expressions
 spanning many lines and many calls to pow. Maybe a small change to the
 Kranc script choosing different options (e.g. enabling CSE, or replacing
 calls to pow by explicit multiplication) could remedy this.

 At the moment I will disable this thorn on Shelob.
