I encounter following error message when configuring php installation, how to solve it?
loading cache ./config.cache
checking for Cygwin environment... no
checking for mingw32 environment... no
checking host system type... i686-pc-linux-gnu
checking for a BSD compatible install... /usr/bin/install -c
checking whether build environment is sane... configure: error: ls -t appears to fail. Make sure there is not a broken
alias in your environment
configure: error: newly created file is older than distributed files!
Check your system clock
What does it means by "build environment is sane"?
