In ~/.rpmmacros I have "%_topdir ~/redhat", when I run the following command:

{{{
R2spec -u http://www.bioconductor.org/packages/release/bioc/src/contrib/Rintact_1.2.0.tar.gz
}}}

Everything seems fine up to ...

{{{
wget http://www.bioconductor.org/packages/release/bioc/src/contrib/Rintact_1.2.0.tar.gz
Saving to: `Rintact_1.2.0.tar.gz'

Do you want to move the source (Rintact_1.2.0.tar.gz) in ~/redhat/SOURCE/? Y/N [Y]
y
cp ..//Rintact_1.2.0.tar.gz to ~/redhat/SOURCE/
Can not copy the source to ~/redhat/SOURCE/
}}}

Why does it look for the file in ..// ?
