installation problem due to libcurl

[vladpetyuk]

Googling relevant issues with curl/libcurl didn't help much. Installation from CRAN went through just fine. Any hints how to fix this are appreciated.

Does this occur with other packages too? Does installing with package ghit work?

[vladpetyuk]

I have not notice the same trouble with other packages so far.

ghit failed too. Perhaps for a different reason.

What worked out is

• downloading ryacas-master.zip directly
• unpacking and renaming directory to Ryacas
• installing from terminal R CMD INSTALL Ryacas
