Looking for extensions...
What extensions do you wish to load dynamically?

Stripping down executable paths...
Creating config.sh...
Doing variable substitutions on .SH files...
Extracting config.h (with variable substitutions)
cflags.SH: Adding -std=c89.
cflags.SH: Adding -Werror=declaration-after-statement.
cflags.SH: Adding -Wextra.
cflags.SH: Adding -Wc++-compat.
cflags.SH: Adding -Wwrite-strings.
cflags.SH: cc = cc
cflags.SH: ccflags = -fwrapv -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
cflags.SH: stdflags = -std=c89
cflags.SH: optimize = -O2
cflags.SH: warn = -Wall -Werror=declaration-after-statement -Wextra -Wc++-compat -Wwrite-strings
Extracting cflags (with variable substitutions)
Not re-extracting config.h
Extracting makedepend (with variable substitutions)
Extracting Makefile (with variable substitutions)
Extracting myconfig (with variable substitutions)
Extracting pod/Makefile (with variable substitutions)
Extracting Policy.sh (with variable substitutions)
Extracting runtests (with variable substitutions)
Configure done.
...
与另一台机器上成功的Configure相比，它没有执行makedepend：
Extracting runtests (with variable substitutions)
Run make depend now? [y]
sh ./makedepend MAKE="make" cflags
执行上面的 makedepend 行给出了一条消息make: *** No rule to make target 'clist'. Stop.。有调试这个的提示吗？非常感激！
