Why is ./Build install destdir=$RPM_BUILD

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am try to create a RPM for the Perl Module YAML::Tiny and in my spec file I have this ...

%build
/usr/perl/bin/perl Build.PL INSTALLDIRS=vendor
./Build
./Build test
%install
rm -rf $RPM_BUILD_ROOT
./Build install destdir=$RPM_BUILD_ROOT
[download]

... and when I run rpmbuild I get this error:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+!!
ERROR: Can't create '/usr/perl-5.14.1/lib/red_perl/YAML'
mkdir /usr/perl-5.14.1/lib/red_perl/YAML: Permission denied at /usr/pe
+rl-5.14.1/lib/5.14.1/ExtUtils/Install.pm line 494

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+!!
[download]

Any help is appreciated. Thanks

I don't mean to sound mean, or anything. But You've already been told what the problem is: `Permission denied` [download] Should it not already be obvious to you; this is a `system` error. Your system (the one your building this on) is trying to tell you that you don't have write privileges to the directory you are attempting to write to. I'ts also possible that "Perl", itself is associated with some user/group, and wouldn't have permission. But, in almost any case, it's you, the user, whos permissions are inherited, that determine what can, and cannot be done on the system. Perhaps doing an su before attempting the install? HTH --Chris UPDATE: I should also add; that you can also make the install, install to a `lib` within your home directory. `make install PREFIX=~/lib` [download] assuming that the directory `lib` already exists within your `~` (Home) directory.

Thanks for your response taint. I learned that YAML::Tiny uses Module::Build::Tiny which does not like `./Build install destdir=$RPM_BUILD_ROOT` [download] so I had to change that line in my spec file to ... `./Build install --destdir=$RPM_BUILD_ROOT` [download]	[reply] [d/l] [select]
