To build perl, you must add the current working directory to your
$xxx environment variable before running make. You can do
this with
- $xxx=\`pwd\`; export $xxx
+ $xxx=\`pwd\`:\$$xxx; export $xxx
for Bourne-style shells, or
setenv $xxx \`pwd\`
for Csh-style shells. You *MUST* do this before running make.
