如何修复由于在Cygwin中找不到合适的Fortran编译器而失败的Python扩展构建？

Question

我正在尝试安装一个Python扩展(hydroclimpy.sourceforge.net)显然需要在安装之前编译一些Fortran。当我为扩展运行build命令时，最后出现一个错误，告诉我找不到合适的Fortran编译器：

我的机器是一个带有Cygwin的windowsxp设备。安装工具已安装。我已经安装了g95以及在Cygwin的安装列表中找到的与Fortran相关的任何东西。/usr/local/bin显示g95和gfortran：

有人能给我一些建议吗？我可以试着把这台机器上的Fortran情况弄清楚，让这个扩展的设置脚本按预期工作？在

如果有帮助，此扩展的安装脚本如下：

您可能想尝试在this python bug中应用该补丁，这允许我在遇到与您描述的完全相同的错误后从源代码构建numpy。在

注意：我是用VS2010编译的，您应该在所有python扩展中也使用它。在
