Rough hints for setting up MUSCLE on Solaris:
Make sure you have libusb, usually in /usr/sfw:
ls -l /usr/sfw/lib/libusb.so
lrwxrwxrwx 1 root other 11 Jan 12 16:02 /usr/sfw/lib/libusb.so -> libusb.so.1
Get PCSC and CCID.
-rwx------ 1 user staff 529540 Jun 16 18:24 ccid-1.0.1.tar.gz
-rwx------ 1 user staff 842654 Jun 16 18:24 pcsc-lite-1.3.1.tar.gz
Unpack pcsc
Run ./configure --enable-libusb=/usr/sfw (??)
gnumake
Make /usr/local writeable for user
gnumake install
Unpack ccid
Run ./configure
gnumake
gnumake install
As root, go to /usr/local/sbin
Run ./pcscd --foreground
