[R-pkg-devel] DLL 'Matrix' not found: maybe not installed for this architecture?

Hello:


 ????? "00check.log" produced by R-devel winbuilder (link below) 
includes the following:


** checking whether the package can be loaded ... ERROR
Loading this package had a fatal error status code 1
Loading log:
Error: package or namespace load failed for 'Ecfun' in 
library.dynam(lib, package, package.lib):
 ?DLL 'Matrix' not found: maybe not installed for this architecture?
In addition: Warning message:
S3 methods 'print.sparseSummary', 'print.diagSummary', 'c.abIndex', 
'c.sparseVector', 'as.array.Matrix', 'as.array.sparseVector', 
'as.matrix.Matrix', 'as.matrix.sparseVector', 'as.vector.Matrix', 
'as.vector.sparseVector' were declared in NAMESPACE but not found
Execution halted


 ????? Is this problem with R-devel winbuilder or me?


 ????? This is for Ecfun on R-Forge that passed their standard tests 
plus on R 3.5.2 on macOS Mojave 10.14.3.


 ????? Thanks,
 ????? Spencer Graves
