Problem with lintpkgsrc

[Marc Baudoin <babafou%babafou.eu.org@localhost>]

Hi again,

For several weeks (months?) now, lintpkgsrc has been printing
some junk such as:

Possible unintended interpolation of @exec in string at (eval 63841) line 1.
Possible unintended interpolation of @exec in string at (eval 63843) line 1.
Possible unintended interpolation of @exec in string at (eval 63844) line 1.
Possible unintended interpolation of @exec in string at (eval 63845) line 1.
[ and much more ]

Is it a bug in lintpkgsrc or bad data in pkgsrc?
