Does "portmaster -f `pkg shlib -qR libperl.so.5.xx" go too deeply?

[Scott Aitken]

Hi,

after upgrading perl5.28 to perl5.30 I ran:

# portmaster -f `pkg shlib -qR libperl.so.5.28`

And it said:

# portmaster -f `pkg shlib -qR libperl.so.5.28`

===>>> Working on:
p5-Net-SSLeay-1.85
p5-Locale-libintl-1.31
p5-Locale-gettext-1.07
net-snmp-5.7.3_20,1
p5-HTML-Parser-3.72
p5-Socket6-0.29

Great. Except it then went on to find any dependencies of those ports. For 
example:

===>>> net-snmp-5.7.3_20,1 4/6 >> mysql55-client-5.5.62_3 >> cmake-3.15.5 >> 
jsoncpp-1.8.1_7 >> scons-3.1.1 >> m4-1.4.18_1,1 >> texinfo-6.7_1,1 >> 
p5-Unicode-EastAsianWidth-12.0 (22/22)

Isn't this a bit heavy handed? Sure net-snmp depends on Perl 5.xx. But m4 
doesn't.

Is there a way to tell postmaster to NOT re-install dependencies?

Thanks,
Scott
