Can't import techfile into abstract (IC6.1.4)

No matter what I do to the techfile attached to the library I want to import into abstract generator, I can't get ERROR ABS-218 to go away:

"There are no vias specified in the technology file. Ensure that the selected constraint group has a ValidVias section or at least one via is specified in the standardViaDefs subsection of the viaDefs section in the technology file. In addition, ensure that the function argument is set to 'cut' for the via in the functions subsection of the layerRules section and then try again."

I am very clear in my techfile for the viaDefs, as well as specifying "cut" for the vias (though, I'm not clear which name "cut" needs to be set for, but it doesn't seem to matter which). Parts of the techfile are at the bottom of this post, but I haven't been able to find anything wrong.

I'd appreciate any ideas; this has become incredibly frustrating.

Note; for the rest of the .tf not shown, basically all of it came from a tech manager file dump (from inside virtuoso), there were just minor changes made to get all of the things abstract wanted in.

viaDefs(
standardViaDefs(
;( viaDefName layer1 layer2 (cutLayer cutWidth cutHeight [resistancePerCut])
; (cutRows cutCol (cutSpace))
; (layer1Enc) (layer2Enc) (layer1Offset) (layer2Offset) (origOffset)
; [implant1 (implant1Enc) [implant2 (implant2Enc) [well/substrate]]])
;( -------------------------------------------------------------------------- )
( M6_M5 METAL5 METAL6 ("VIA56" 0.3 0.3)
(1 1 (0.3 0.3))
(0.1 0.1) (0.5 0.5) (0.0 0.0) (0.0 0.0) (0.0 0.0)
; (more here not shown)
)
)


As well as:
layerRules(
functions(
( VIA56 "cut" 10 ) ; not sure if it should use cutLayer
( M6_M5 "cut" 10 ) ; or viaDefName
; plenty of others
)
)
