How to manage multiple package dependencies with checkinstall?

I have a package that I've been building using checkinstall for a while now, and I wanted to automate it (pass the values in via command line instead of typing the selection, pasting the value in, etc...)

I am not sure if this is a checkinstall bug, or not, but how can I include multiple packages via the command line --requires option. It seems to barf if I include the minimum version of a package (for exmple --requires="libvte9 (>= 0.28.2)"), or multiple packages at once (for example --requires "libvte9, libc6")

Has anyone had better success with the command line arguments for multiple packages? Am I doing something wrong, or is this a bug.

Note: If I run the script, and choose the requires option (10), and paste my entire line with multiple packages and minimum versions (such as libvte9 (>= 0.28.2), libc6 (>= 2.13), it works fine, it just seems to be on the command line that it's having issues. Also this is with building a debian package, using the -D option.

Solution

After reading Aleks-Daniel Jakimenko-A.'s answer, Reallumpi's one and doing some tests on a real life case, here is what you should do:

use , (comma) without spaces to separate required packages ;
escape ( and ) parenthesis when specifying package's version ;
escape > (greater sign) when specifying package's version ;

Example

make && sudo -k checkinstall \
    --pkgsource="https://github.com/raboof/nethogs/" \
    --pkglicense="GPL2" \
    --deldesc=no \
    --nodoc \
    --maintainer="$USER\\<$USER@$HOSTNAME\\>" \
    --pkgarch=$(dpkg \
    --print-architecture) \
    --pkgversion="0.8.1" \
    --pkgrelease="SNAPSHOT" \
    --pkgname=nethogs \
    --requires="libc6 \(\>= 2.4\),libgcc1 \(\>= 1:4.1.1\),libncurses5 \(\>= 5.5-5~\),libpcap0.8 \(\>= 0.9.8\),libstdc++6 \(\>= 4.1.1\),libtinfo5" \
    make install

Output
