Tailscale clean install fails due to perl5 version

[russd]

Hi, when trying to do a clean   make install   of Tailscale using their OPNSense documentation https://tailscale.com/kb/1097/install-opnsense on OPNsense 25.7.2-amd64 the install fails with


===>   help2man-1.49.3_1 depends on package: perl5>=5.42.r<5.43 - not found
===>  Configuring for perl5-5.42.0

....

Support DTrace if available? [y]
Where is the dtrace executable? (''name ok) [/usr/sbin/dtrace]

*** Configure:  Fatal Error:  /usr/sbin/dtrace doesn't support -h flag
***
*** Your installed dtrace doesn't support the -h switch to compile a D
*** program into a C header. Can't continue.

Manually forcing an install of latest perl5-5.42.0 then allows the make process to complete

root@opnsense:/usr/ports/security/tailscale # pkg add -f https://pkg.freebsd.org/FreeBSD:14:amd64/latest/All/perl5-5.42.0_1.pkg
Fetching perl5-5.42.0_1.pkg: 100%   16 MiB  16.7MB/s    00:01
Installing perl5-5.42.0_1...
package perl5 is already installed, forced install
Extracting perl5-5.42.0_1: 100%

However, this obviously leaves perl at an unsupported version, and subsquent package installs (os-upnp for example) downgrade the packages :(

New packages to be INSTALLED:
   miniupnpd: 2.3.9_1,1 [OPNsense]
   os-upnp: 1.7 [OPNsense]

Installed packages to be DOWNGRADED:
   perl5: 5.42.0_1 -> 5.40.3_2 [OPNsense]

Number of packages to be installed: 2
Number of packages to be downgraded: 1

Installed packages to be REMOVED:
   bash: 5.3.3_1
   bison: 3.8.2_2,1
   gmake: 4.4.1
   go124: 1.24.6
   help2man: 1.49.3_1
   m4: 1.4.19_1,1
   p5-Locale-libintl: 1.35
   p5-Text-Unidecode: 1.30
   p5-Unicode-EastAsianWidth: 12.0
   texinfo: 7.1_12,1



What's the process for requesting an updated perl5 package in the OPNSense repo please?

I have updated the Tailscale github issue raised yesterday on this also  https://github.com/tailscale/tailscale/issues/16923   but I think the simplest solution is to upgrade the perl5 package in OPNSense, assuming it doesn't break other things of course!

Thanks, Russ

Their documentation is outdated and for the past 2 years have been unable to update it even though they are aware of the problem...

Just install the plugin.

OK, got it, didn't spot there was a plugin as I didn't have the 'community' box ticked!

Just FYI whenever FreeBSD changes the Perl version this breakage is expected. 25.7.3 will switch Perl version to match FreeBSD again.


Cheers,
