make gomod-vendor XML errors

Hello,

I'm trying to update security/gopass
<https://www.freshports.org/security/gopass/> from 1.13.1 to 1.14.0 and
'make gomod-vendor'(1) gives the list of dependency but end with:

---
(...)
urfave:cli:v2.4.0:urfave_cli_v2/vendor/github.com/urfave/cli/v2 \
xrash:smetrics:039620a65673:xrash_smetrics/vendor/github.com/xrash/smetrics

# Errors found during processing:
#       XML syntax error on line 12: expected attribute name in element
---

(1) Same results with:
---
cd security/gopass
make extract
cd work/gopass-1.14.0
go mod vendor
modules2tuple vendor/modules.txt > ../../new_tuple.txt
---

Building port:

---
===>  Building gopass from .
internal/action/clone.go:10:2: cannot find package "." in:

/usr/home/nunotex/Work/freebsd/ports/security/gopass/work/gopass-1.14.0/vendor/
bitbucket.org/creachadair/stringset
*** Error code 1

Stop.
make[1]: stopped in /usr/home/nunotex/Work/freebsd/ports/security/gopass
*** Error code 1
---

Any clues on how to fix this?
Should this be an upstream problem? I have searched gopass issues and
didn't found any issue at all.

Thanks,

Nuno Teixeira
