Remmina RDP for Slackware from SBo

i am on Slackware 14.2, kernel 5.4.17-smp

I am STILL.... 5weeks later, trying to install Remmina for the Google/Coursera class I am taking online. I'm sure most would have given up by now but, I have a burning desire to 'not let this one go' especially if the Google IT Support Pro certification can help me land work in 2021!

I have attached the terminal screens from the folders I have been working in:

./Downloads
./tmp

from SlackBuild.org or SBo I have downloaded and installed:

json-glib
vala
pcre2
opus
spice
spice-protocol
six
pyparsing
ffmpeg
freerdp
libsodium -- all have installed just fine.

Still required to run remmina:

spice-gtk
vte3 --- both have "run-time" errors as seen in one of the attachments and
in the #code# boxes below....

bash-5.0#when I run ./vte3.SlackBuild

i get this error....

Code:^Cmake[3]: *** [/usr/share/vala/Makefile.vapigen:61: vte-2.91.vapi] Interrupt
make[2]: *** [Makefile:448: all-recursive] Interrupt
make[1]: *** [Makefile:574: all-recursive] Interrupt
make: *** [Makefile:481: all] Interrupt

bash-5.0# ^C
bash-5.0#Pretty much the same thing happens when I run -

./spice-gtk.SlackBuild

in the ~/#Downloads/spice-gtk folder

So.... any ideas of what I can do to finish killing this bear with a Bowie
knife and some really good boots..... ???

thanks,
