building 7.4 with plperl

Before I go deep into this - does anyone have the quick fix for this ?

Some facts - the 7.3.4 version of plperl.c has the same errors in the
7.4 tree.
The 7.4 version of plperl.c (with some error handling API calls
commented out) compiles fine in the 7.3.4 tree.
(Same machine - same install of perl !) Points to using some alternate
perl API probably by macro collision ?
