May be you aren't loading it, while you think that you do. Please observe:

% perl -le 'use warnings; use strict; use Apache2::Const; \
sub foo {return Apache2::Const::OK }'

% perl -le 'use warnings; use strict; \
sub foo {return Apache2::Const::OK }'
Bareword "Apache2::Const::OK" not allowed while "strict subs" in use at -e 
line 1.
Execution of -e aborted due to compilation errors.

Try:

warn $INC{'Apache2/Const.pm'}

somewhere in your code. It should show you the file that was loaded.

If everything else fails, if you can use the problem reporting skeleton 
[1] and reproduce the problem with it (adjusting it by adding some minimal 
code). Please send it here and we will look at it).
