Проблема в configure

[Pechnikov Alexey <pechnikov@sandy.ru>]

Команда ./configure выдает вот такую ошибку:

checking system version (for dynamic loading)... ./configure: line 3789: 
syntax error near unexpected token `('
./configure: line 3789: `  case `(ac_space=' '; set | grep ac_space) 2>&1` in'


Эта ошибка возникает в следующем блоке кода:


# The following way of writing the cache mishandles newlines in values,
# but we know of no workaround that is simple, portable, and efficient.
# So, don't put newlines in cache variables' values.
# Ultrix sh set writes to stderr and can't be redirected directly,
# and sets the high bit in the cache file unless we assign to the vars.
(set) 2>&1 |
  case `(ac_space=' '; set | grep ac_space) 2>&1` in
  *ac_space=\ *)
    # `set' does not quote correctly, so add quotes (double-quote substitution
    # turns \\\\ into \\, and sed turns \\ into \).
    sed -n \
      -e "s/'/'\\\\''/g" \
      -e "s/^\\([a-zA-Z0-9_]*_cv_[a-zA-Z0-9_]*\\)=\\(.*\\)/\\1=\${\\1='\\2'}/p"
    ;;
  *)
    # `set' quotes correctly as required by POSIX, so do not add quotes.
    sed -n -e 's/^\([a-zA-Z0-9_]*_cv_[a-zA-Z0-9_]*\)=\(.*\)/\1=${\1=\2}/p'
    ;;
  esac >> confcache


Есть ли способ починить этот код? Или можно в каком-то другом интерпретаторе 
его выполнить?
