Strange dependency problem installing GIT 0.99.7

Strange dependency problem installing GIT 0.99.7

[Peter Williams]

When I tried to install GIT 0.99.7 from the rpm package (on a Fedora 
Core 4 system) I got the following error message:

error: Failed dependencies:
         perl(String::ShellQuote) is needed by git-core-0.99.7-1.i386

So I installed String::ShellQuote from CPAN and tried again with the 
same result.  So I then rebuilt the rpm on my system and still got the 
same error message.  So I've installed the rpm using the --nodeps option 
but would like to test whether it is successfully finding 
String::ShellQuote.  Which command(s) would exercise this perl package?

$ git grep ShellQuote
git-archimport.perl:42:use String::ShellQuote;

Sorry for the gotcha.  Any RPM experts to offer advice?

That command finds ShellQuote OK which more or less confirms that it's 
just an rpm problem.

Peter,

You need to install ShellQuote with rpm rather than installing it directly
from CPAN.  You can pick up a rpm version of ShellQuote from several
places, here's one:  http://tinyurl.com/7p7ey

IMHO rpm shouldn't care how ShellQuote got there unless it (how it got 
there) is stated as an explicit dependency in the spec file (which it 
isn't).  So I still think this is a bug in rpm's (automatic) dependency 
mechanism that needs fixing.

dependencies in the spec file even though other equally ubiquitous 
packages are.

But rpm resolves dependencies by looking in the rpm database not by
checking the filesystem.   You can actually disable the automatic perl
dependency detection when creating the rpm, but that probably isn't
desirable.

At least on Red Hat/Fedora machines you can create your own rpms directly
from CPAN so it's not too big a restriction:

$ cpan2rpm String::ShellQuote
$ cd ~/rpm/RPMS/noarch
$ sudo rpm -ivh perl-String-ShellQuote-1.03-1.noarch.rpm

Which is all you need to download, package and install the perl module.

There is special handling for perl detection within the rpmbuild
procedure, so perl will be added automatically where many others won't be.

Unfortunately it doesn't work that way (and this is the wrong mailing 
list to discuss it on.)  Anyway, the best way to install CPAN modules on 
an RPM-based system is to use cpan2rpm.

If it needs ShellQuote, it is required. RPM does know only about things in
its database (i.e., rpm-installed).
