Re^4: Can't locate IO/Scalar.pm in @INC (@INC contains: /opt/rocks/lib/perl5/5.8.8/

I also found that directories in @INC mentioned in error message and that gotten by using "perl -V" are some different.

from error message:

if I put Scalar.pm in '/home/donghe/iprscan/lib', this problem is solved! however '/home/donghe/iprscan/lib' is not included in the @INC showed by using 'perl -V'. do you know the reason?

`perl -V` lists the hardcoded initial value for `@INC`. The error message includes `@INC` as it was when the `require` was executed. `@INC` can be modified directly, or by using env var `PERL5LIB`, env var `PERLLIB`, module lib or the command line option `-I` (via command line, shebang or env var PERLOPTS).

Did you show the entire output of 'perl -V' ? Usually the current working directory ('.') is in @INC, and if '/home/donghe/iprscan/lib' is your current working directory, then '/home/donghe/iprscan/lib/IO/Scalar.pm' would be found by `use IO::Scalar;`. (Note that the @INC, as reported by the error message does include '.') However, it can never make any sense that '/home/donghe/iprscan/lib/Scalar.pm' would be found by attempting to `use IO::Scalar;` And whatever happened to the perl that's in /opt (referenced in your original post) ?
