This is some really obscure issue. I'm maintaining docbook-xsl. I'm
currently building version 1.71.0.dfsg.1-1. When I build this version
with pbuilder, the file
/usr/share/xml/docbook/stylesheet/nwalsh/slides/keynote/xsltsl/cmp.xsl
gets executable file permissions (0755). The checkout is made from CVS
(using cvs-buildpackage). The file itself has only 0600 file permissons
(definitely no executable tag). When I build the package with debuild,
everything is ok. But when I use pbuilder, the file get's executable
flags added, which results in a lintian warning.

You can try it youself (with cvs-buildpackage installed, and a SID
chroot):

$ cvs -z3 -d:pserver:anonymous at cvs.alioth.debian.org:/cvsroot/debian-xml-sgml \
  co -d pkg-doc-xsl docbook-xsl

$ cd pkg-docbook-xsl

$ cvs-buildpackage -C'pdebuild'

The result is:
$ dpkg-deb -c docbook-xsl_1.71.0.dfsg.1-1_all.deb | grep cmp.xsl
- -rwxr-xr-x root/root 11589 2006-07-04 06:35 ./usr/share/xml/docbook/stylesheet/nwalsh/slides/keynote/xsltsl/cmp.xsl

W: docbook-xsl: executable-not-elf-or-script ./usr/share/xml/docbook/stylesheet/nwalsh/slides/keynote/xsltsl/cmp.xsl
N:
N:   This executable file is not an ELF format binary, and does not start
N:   with the #! sequence that marks interpreted scripts. It might be a sh
N:   script that fails to name /bin/sh as its shell.

N:   Refer to Policy Manual, section 10.4 for details.

But when I simply build it with debuild:
dpkg-deb -c docbook-xsl_1.71.0.dfsg.1-1_all.deb | grep cmp.xsl
- -rw-r--r-- root/root 11589 2006-07-04 06:35 ./usr/share/xml/docbook/stylesheet/nwalsh/slides/keynote/xsltsl/cmp.xsl

The source should also be soon in Debian. So you can avoid
cvs-buildpackage and instead use apt-get source.

Or if there is any other way to help to solve this issue, please just
tell me and I will do my best to provide the information you need. But
this is really obscure.

Regards, Daniel
