Comment(by captsolo at gmail.com):

 Can confirm the same bug (error: `CPPFLAGS' has changed since the previous
 run).

 clisp: 2.43
 MacPorts: 1.6.0
 OS X: 10.5.4

 However, this error only appears if the libsigsegv 2.5 port (which clisp
 depends on) was installed on the same go. Or if retrying installing clicp
 after this error happened, without doing "port clean". Would be good to
 get this fixed, but for now there are a couple of ways to work around it:

 a) install libsigsegv separately, then install clisp

 b) if the error occured already, do "port clean --all clisp" and try to
 install it again
